cellfinder
cellfinder is software for automated 3D cell detection in very large 3D images (e.g., serial two-photon or lightsheet volumes of whole mouse brains).
There are three different ways to interact and use it, each with different user interfaces and objectives in mind.
For more details, head over to the documentation website.
At a glance:

There is a command-line interface called brainmapper that integrates with brainreg for automated cell detection and classification. You can install it through brainglobe-workflows.
There is a napari plugin for interacting graphically with the cellfinder tool.
There is a Python API to allow users to integrate BrainGlobe tools into their custom workflows.

Installation
You can find the installation instructions on the BrainGlobe website, which will go into more detail about the installation process if you want to minimise your installation to suit your needs.
However, we recommend that users install cellfinder either through installing BrainGlobe version 1, or (if you also want the command-line interface) installing brainglobe-workflows.
```bash
If you want to install all BrainGlobe tools, including cellfinder, in a consistent manner with one command:
pip install brainglobe>=1.0.0
If you want to install the brainmapper CLI tool as well:
pip install brainglobe-workflows>=1.0.0
```
If you only want the cellfinder package by itself, you can pip install it alone:
bash
pip install cellfinder>=1.0.0
Be sure to specify a version greater than version v1.0.0 - prior to this version the cellfinder package had a very different structure that is incompatible with BrainGlobe version 1 and the other tools in the BrainGlobe suite.
See our blog posts for more information on the release of BrainGlobe version 1.

napari-sim-processor






A Napari plugin for the reconstruction of Structured Illumination Microscopy (SIM) with GPU acceleration (pytorch/cupy if installed).
Currently supports:  
   - conventional SIM data with a generic number of angles and phases (typically, 3 angles and 3 phases are used for resolution improvement in 2D, but any combination can be processed by the widget)
   - hexagonal SIM data with 7 phases, as used in this publication.
   - 3D SIM, for resolution enhancement in three dimensions. This is available in the 3dSIM branch  
The SIM processing widget accepts image stacks organized in 5D (angle,phase,z,y,x).
The reshape widget can be used to easily reshape the data if they are not organized as 5D (angle,phase,z,y,x).
For 3D stacks (raw images) with multiple z-frames, a batch reconstruction method is available, as described here.
Syntetic raw-image stacks of Structured Illumination Microscopy can be easily simulated using the napari SIMulator pluging.

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation
You can install napari-sim-processor via pip:
pip install napari-sim-processor

To install latest development version :
pip install git+https://github.com/andreabassi78/napari-sim-processor.git

Usage
1) Open napari. 
2) Launch the reshape and sim-processor widgets.
3) Open your raw image stack (using the napari built-in or your own file opener).

4) If your image is ordered as a 5D stack (angle, phase, z-frame, y, x) go to point 6. 
5) In the reshape widget, select the actual number of acquired angles, phases, and frames (red arrow) and press Reshape Stack.
 Note that the label axis of the viewer will be updated (green arrow).

6) In the sim-reconstruction widget press the Select image layer button. Note that the number of phases and angles will be updated (blue arrow). 
7) Choose the correct parameters of the SIM acquisition (NA, pixelsize, M, etc.) and processing parameters (alpha, beta, w, eta, group):
   - w: parameter of the Weiner filter.
   - eta: constant used for calibration. It should be slightly smaller than the carrier frequency (in pupil radius units).
   - group: for stacks with multiple z-frames, it is the number of frames that are used together for the calibration process.
For details on the other parameters see here.
8) Calibrate the SIM processor, pressing the Calibrate button. This will find the carrier frequencies (red circles if the Show Carrier checkbox is selected), the modulation amplitude and the phase, using cross correlation analysis.
9) Click on the checkboxes to show the power spectrum of the raw image (Show power spectrum) or the cross-correlation (Show Xcorr), to see if the found carrier frequency is correct.

Napari viewer showing the power spectrum of the raw stack. The pupil circle is in blue. A circle corresponding to eta is shown in green.

10) Run the reconstruction of a single plane (SIM reconstruction) or of a stack (Stack reconstruction). After execution, a new image_layer will be added to the napari viewer. Click on the Batch reconstruction checkbox in order to process an entire stack in one shot. Click on the pytorch checkbox for gpu acceleration.

GPU processing
The underlying processing classes will use numpy (and FFTW if available) for 
its calculations. For GPU accelerated processing you need to have either the 
PyTorch (tested with torch v1.11.0+cu113) or the CuPy (tested with cupy-cuda113 
v10.4.0) package installed.  Make sure to match the package cuda version to the CUDA library 
installed on your system otherwise PyTorch will default to CPU and CuPy will not work at all.  
Both packages give significant speedup on even relatively modest CUDA GPUs compared 
to Numpy, and PyTorch running on the CPU only can show improvements relative to numpy 
and FFTW. Selection of which processing package to use is via a ComboBox in the 
napari_sim_processor widget.  Only available packages are shown. 
Other than requiring a CUDA GPU it is advisable to have significant GPU memory 
available, particularly when processing large datasets.  Batch processing is the 
most memory hungry of the methods, but can process 280x512x512 datasets on a 4GB GPU.

napari-clusters-plotter










A napari-plugin for clustering objects according to their properties.

Usage
Starting point
For clustering objects according to their properties, the starting point is a grey-value image and another layer containing derived measurements in the .features property. Here are the supported layer types along with examples of what they may represent:
1. Labels layer containing a label image representing a segmentation of objects.
2. Points layer containing points representing centroid coordinates of objects.
3. Surface layer containing a surface representing a segmentation of an object.
4. Labels layer containing a time-lapse label image representing tracking results, where each label number/color correspond to a unique track ID.
Check the examples data folder to learn how to load these data with code.
1. Labels layer with Segmentation Results
The label image should not contain objects with the label 0 as these objects cannot be separated from the background, which is 0 as well in many images and would lead into erroneous behaviour when performing the clustering.
For segmenting objects, you can for example use the Voronoi-Otsu-labelling approach
in the napari plugin napari-segment-blobs-and-things-with-membranes.

In case you have 2D time-lapse data you need to convert it into a suitable shape using the menu Tools > Utilities > Convert 3D stack to 2D time-lapse (time-slicer) (documentation).
Measurements
The first step is deriving measurements from the labeled image and the corresponding pixels in the grey-value image.
Use the menu Tools > Measurement tables > Regionprops (scikit-image, nsr) to get to the measurement widget (documentation).
Select the image, the corresponding label image and the measurements to analyse and click on Run.
A table with the measurements will open and afterwards, you can save and/or close the measurement table.
At this point it is recommended to close the table and the Measure widget to free space for following steps.
You can also load your own measurements. You can do this using the menu Tools > Measurement > Load from CSV (nsr).
If you load custom measurements, please make sure that there is a label column that specifies which measurement belongs to which labeled object.
Make sure to avoid the label 0 as this is reserved for the background. Tables for time-lapse data need to include an additional column named frame.
Plotting
Once measurements were saved in the labels layer which was analysed, you can then plot these measurements using the menu Tools > Visualization > Plot measurements (ncp).
In this widget, you can select the labels layer which was analysed and the measurements which should be plotted
on the X- and Y-axis. Click on Plot to draw the data points in the plot area.

Under advanced options, you can also select the plot type histogram which will visualize a 2D histogram. 2D histogram visualization is recommended if you have a very high number of data points.

If you choose the same measurement for the X and the Y axis, a histogram will be shown.

Under advanced options you will also find the checkbox determining whether not-selected data points should be hidden (shown in grey) or automatically
clustered as another cluster.
Manual clustering
You can manually select a region in the plot. To use lasso (freehand) tool use left mouse click, and to use a
rectangle - right click. The resulting manual clustering will also be visualized in the original image. To optimize
visualization in the image, turn off the visibility of the analysed labels layer.

Hold down the SHIFT key while annotating regions in the plot to manually select multiple clusters.

Saving manual clustering
Manual clustering results can be saved by going to Tools > Measurement > Show table (nsr), and clicking on Save as csv.
The saved table will contain a "MANUAL_CLUSTER_ID" column. This column is overwritten every time different clusters are manually selected.
Time-Lapse analysis
When you plot your time-lapse datasets you will notice that the plots look slightly different.
Datapoints of the current time frame are highlighted in bright color and you can see the datapoints move through the plot while you navigate through time:

You can also manually select groups using the lasso tool and plot a measurement per frame and see how the group behaves in time.
Furthermore, you could also select a group in time and see where the datapoints lie in a different feature space:

If you have custom measurements from tracking data where each column specifies measurements for a track instead of a label at a specific time point, the frame column must not be added. Check below how tracking data and features should look like.
2. Points Layer with Coordinates
The Points layer typically contains coordinates of objects of interest (for example, object centroids).
To get these coordinates, you can apply spot detection algorithms (check references here with scikit-image, here with pyclesperanto and here for the spotflow plugin) or, if you have segmentation results, use objects centroids as coordinates. This last approach can be done via Tools > Points > Create points from labels centroids (nppas) from the napari-process-points-and-surfaces plugin:

You can load object features to these points by assigning them to the .feature attribute of the Points layer, like this in Python:
points_layer.features = features_table
The number of rows in the table should match the number of points.
You can cluster these features using the same algorithms explained furhter down, or manually, and get points colored accordingly, like shown below:

Check also this notebook to learn how to load these data from code.
3. Surface Layer with Segmentation Results
The Surface layer could contain a surface representing a segmentation result.
To generate this surface from a labeled image containing the segmentation results, a classical algorithm is the Marching Cubes. It is available in scikit-image, and you can also apply it via Tools > Surfaces > Create surface from any label (marching cubes, scikit-image, nppas) from the napari-process-points-and-surfaces plugin. Choose which label id number you want to turn into a surface and click on Run:

You will notice that the surface layer will be created.

You can derive quantitative measurements from the vertices of a surface via Tools > Measurement tables > Surface quality table (vedo, nppas) from napari-process-points-and-surfaces plugin:

Surface vertex measurements can be plotted and classified the same way with the plotter (Tools > Visualization > Plot measurements (ncp)):

Check this notebook to learn how to load these data from code.
4. Labels Layer with Tracking Results
The Labels layer can be also used to display tracking results.
These notebooks show you examples of how to load and format tracking features from Mastodon in a way compatible with napari-clusters-plotter.
For example, if you have a time-lapse labeled image where each label number represents a unique track ID, you can load tracking features to this Labels layer and use the plotter to cluster them. In the 'gif' below, the Tracks layer is NOT used for clustering, it is just shown along as a convenience. There is currently no support for the Tracks layer.

Check this notebook to learn how to load these data from code.
Dimensionality reduction
For getting more insights into your data, you can reduce the dimensionality of the measurements, using these algorithms:
* Uniform Manifold Approximation Projection (UMAP)
* t-distributed stochastic neighbor embedding (t-SNE)
* Principal Component Analysis (PCA)
* Non-linear dimensionality reduction through Isometric Mapping (Isomap)
* Multi-dimensional Scaling (MDS)
To apply them to your data use the menu Tools > Measurement post-processing > Dimensionality reduction (ncp).
Select the label image that was analysed and in the list below, select all measurements that should be dimensionality reduced.
By default, all measurements are selected in the box.
You can read more about parameters of both algorithms by hovering over question marks or by clicking on them.
When you are done with the selection, click on Run and after a moment, the table of measurements will re-appear with two additional columns representing the reduced dimensions of the dataset.
These columns are automatically saved in the labels layer and can be further processed by other plugins.

Afterwards, you can again save and/or close the table.
Clustering
If manual clustering, as shown above, is not an option, you can automatically cluster your data, using these implemented algorithms:
* k-means clustering (KMEANS)
* Hierarchical Density-Based Spatial Clustering of Applications with Noise (HDBSCAN)
* Gaussian Mixture Model (GMM)
* Mean Shift (MS)
* Agglomerative clustering (AC)
Therefore, click the menu Tools > Measurement post-processing > Clustering (ncp),
select the analysed labels layer.
Select the measurements for clustering, e.g. select only the UMAP measurements.
Select the clustering method KMeans and click on Run.
The table of measurements will reappear with an additional column ALGORITHM_NAME_CLUSTERING_ID containing the cluster
ID of each datapoint.

Afterwards, you can save and/or close the table.
Plotting clustering results
Return to the Plotter widget using the menu Tools > Visualization > Plot measurement (ncp).
Select UMAP_0 and UMAP_1 as X- and Y-axis and the ALGORITHM_NAME_CLUSTERING_ID as Clustering, and click on Plot.

Installation
Devbio-napari installation
The easiest way to install this plugin is to install the devbio-napari plugin collection. The napari-clusters-plotter is part of it.
Minimal installation


Get a python environment, e.g. via mini-conda.
  If you never used mamba/conda environments before, please follow the instructions
  in this blog post first.


Create a new environment, for example, like this:


mamba create --name ncp-env python=3.9

Activate the new environment via conda:

mamba activate ncp-env

Install napari, e.g. via conda:

mamba install -c conda-forge napari
Afterwards, you can install napari-clusters-plotter, e.g. via conda:
mamba install -c conda-forge napari-clusters-plotter
Troubleshooting installation

Error: Could not build wheels for hdbscan which use PEP 517 and cannot be installed directly

This can happen if you used pip for the installation. To solve this error, install hdbscan via conda before installing the plugin:
mamba install -c conda-forge hdbscan

ValueError: numpy.ndarray size changed, may indicate binary incompatibility. Expected 96 from C header, got 88 from PyObject

Similar to the above-described error, this error can occur when importing hdbscan through pip or in the wrong order. This can be fixed by installing packages separately through conda and in the following order:
bash
mamba install -c conda-forge napari hdbscan
pip install napari-clusters-plotter

minimum vesicles size: The minimum size of the vesicles to detect. Smaller detected vesicles are removed.
membrane erosion: The size of the disk radius used for eroding the cell. This is used to remove the external membrane. This parameter scales when downsizing the image, for more information see 'downsizing ratio' parameter.
closing size: The size of the disk radius used for closing the cell. This is used to fill holes in the cell. This parameter scales when downsizing the image, for more information see 'downsizing ratio' parameter.
clip: If set to zero, no standardization is performed. Otherwise, the standard deviation of the image is set to n_sigma * the standard deviation of the image, the image is standardized and its values are clipped to the range [-1, 1] in order to remove outliers. The higher the value of n_sigma, the less outliers are removed. This operation can lead to a better detection of the cell.
downsampling ratio: The downsampling ratio used for the downsampled image. This is used to speed up the computation. Downsampling the image have impact in reducing the resolution of erosion and closing e.g. for a downsize ratio of 2, setting the erosion size to 3 will result in an erosion size of 6.
display cell detection: If set to True, the cell detection is displayed in the viewer instead of the vesicle detection.


Click on the "Segment" button to start the segmentation. This can take few seconds or minutes depending on the size of the data. The result is added to the viewer as below.

Key Features:

Simple, user-friendly interface within napari
Compatible with SAMCell models in multiple formats (.pt, .bin, .safetensors)
Support for both SAM-ViT-Base and SAM-ViT-Large model architectures
Adjustable segmentation parameters for fine-tuning
Real-time visualization of results
Distance map visualization for analyzing cell proximity
Full integration with napari's layer system
Enhanced sliding window algorithm with advanced blending for seamless segmentation of large images

What's New in v1.0.0:

Support for multiple model file formats (.pt, .bin, .safetensors)
Improved sliding window algorithm with smooth blending between crops
Better handling of small images and edge cases
Enhanced error recovery and logging
Multiple threshold testing capability
Optimized default thresholds for better segmentation results
Support for both SAM-ViT-Base and SAM-ViT-Large model variants

Installation
You can install samcell-napari via [pip]:
bash
pip install samcell-napari
To install latest development version:
bash
pip install git+https://github.com/saahilsanganeriya/samcell-napari.git
Usage


Start napari
   bash
   napari


Load your image in napari


Open the SAMCell plugin:
   Plugins > samcell-napari > SAMCell Segmentation


Provide the path to your SAMCell model file (supports .pt, .bin, or .safetensors formats)


You can download pre-trained models from the official SAMCell release page


Adjust parameters if needed:

Cell peak threshold: Higher values detect fewer cells (default: 0.47)
Cell fill threshold: Lower values create larger cells (default: 0.09)

Crop size: Size of image crops for processing (default: 256)


Click "Run Segmentation"


View the segmentation results in napari as a Labels layer


Requirements

Python 3.8 or higher
napari 0.4.14 or higher
PyTorch 1.9 or higher
transformers 4.20.0 or higher
CUDA-capable GPU recommended for faster processing

Model Compatibility
The plugin is compatible with SAMCell model files in multiple formats:
- PyTorch model files (.pt)
- Binary model files (.bin) - including the standard pytorch_model.bin
- SafeTensors files (.safetensors) - a safer alternative to PyTorch's pickle-based format
The plugin supports models based on:
- SAM-ViT-Base architecture - Primary model type
- SAM-ViT-Large architecture - Fallback if a model doesn't load with base architecture
Pre-trained models can be downloaded from the official SAMCell release page.
Recommended models include:
- SAMCell1.0-Cellpose-cyto: Trained on the Cellpose cytoplasm dataset
- SAMCell1.0-livecell: Trained on the LiveCELL dataset
These models are part of the release assets for the paper "SAMCell: Generalized Label-Free Biological Cell Segmentation with Segment Anything".
How It Works
SAMCell operates using an enhanced sliding window approach to process large images:

The image is divided into overlapping crops with intelligent handling of image boundaries
Each crop is processed through a SAM-based model
A distance map is created, representing cell centers and boundaries
The crops are stitched back together with smooth blending for seamless transitions
The distance map is processed to extract individual cell masks using watershed segmentation
Results are displayed in napari as labels

Technical Details
Model Type Detection
The plugin intelligently determines the appropriate SAM model architecture:
1. First tries to load the model with SAM-ViT-Base architecture
2. If that fails, automatically falls back to SAM-ViT-Large
3. This ensures maximum compatibility with various pre-trained models
Sliding Window Algorithm
The plugin uses an advanced sliding window algorithm that:
- Handles images of any size, including those smaller than the crop size
- Creates appropriate overlaps between crops to ensure no cells are missed
- Uses a cosine-based blending mask to create smooth transitions between crops
- Fills any potential gaps using nearest neighbor interpolation
Multiple Threshold Testing
For researchers who want to optimize segmentation parameters, the plugin includes a batch processing capability to test multiple threshold combinations at once (available via the API).

napari-ome-zarr-navigator 






A plugin to browse OME-Zarr plates by conditions and load images, labels and features from ROIs
Usage
The ImageBrowser recognizes OME-Zarr plates that were loaded via napari-ome-zarr and allows the selection of wells in the multiwell plate.

The ImageBrowser allows to zoom to a given well ("Go to well") & puts a white bounding box around the selected well.

Using prototype condition tables (to be defined better, see sample data provided by the plugin orthe example in the test data below), the ImageBrowser allows for selecting subsets of the well list based on conditions defined in the condition table. The operetta-compose Fractal task package provides a task to create such condition tables.

The ROI loader (formerly available separately as a napari plugin) can be used standalone or integrated with the ImageBrowser. If a well is selected from the ImageBrowser, all the images in that well can be loaded via the ROI loader.
This supports:
- Loading images from different multiplexing acquisitions
- Loading any ROI based on Fractal ROI tables
- Loading label images
- Loading feature measurements (based on Fractal feature tables in the AnnData format)
This approach of loading label images and feature data has been optimized for and tested with the napari feature classifier.

This plugin is meant to work well for OME-Zarr files generated by Fractal.

Test data
Test data is available at https://zenodo.org/records/11262587
Installation
You can install napari-ome-zarr-navigator via pip:
pip install napari-ome-zarr-navigator

napari-phasors






A simple plugin to do phasor analysis in napari. Based on the phasorpy library.
Jump to Intallation


Usage
napari-phasors is composed of a few widgets that allow reading a few specific FLIM and hyperspectral file formats, perform phasor analysis, and display and export the results of manual phasor selections.
Sample Data
Two sample datasets for FLIM are provided, along with their corresponding calibration images. Additionally, a paramecium image is included as sample data for hyperspectral analysis.

Phasor Analysis
Plot FLIM Data
FLIM phasor data can be plotted as a 2D histogram or scatter plot. The colormap, the number of bins and the scale of the colors can be customized.
Filtering and thresholding can also be applied to process phasor data and the mean intensity image. 

Plot Hyperspectral Data
Hyperspectral phasor data can also be plotted as a 2D histogram or scatter plot and visualized in the full universal circle.

Apparent Lifetime Display
A FLIM image can be colormapped according to the phase or modulation apparent lifetime. A histogram is also created for visualization of the distribution of apparent lifetimes of the FLIM image.

Phasor Calibration
FLIM images can be calibrated using a reference image acquired under the same experimental parameters. This reference image should consist of a homogeneous solution of a fluorophore with a known fluorescence lifetime and the laser frequency used in the experiment. This ensures accuracy and consistency in lifetime measurements.

Phasor Custom Import
Supported file formats (.tif, .ptu, .sdt, .fbd, .lsm, .ome.tif) can be read and transformed to the phasor space. Additional options, such as the harmonics, channels and frames, can be specified depending on the file format to be read.

Phasor Export
The average intensity image and the phasor coordinates can be exported as OME-TIF files that can be read by napari-phasors and PhasorPy. Alternatively, the phasor coordinates, as well as the selections (cursors) can be exported as a CSV file.

Installation
You can install napari-phasors via pip. Follow these steps from a terminal.

VollSeg Napari Plugin





VollSeg is more than just a single segmentation algorithm; it is a meticulously designed modular segmentation tool tailored to diverse model organisms and imaging methods. While a U-Net might suffice for certain image samples, others might benefit from utilizing StarDist, and some could require a blend of both, potentially coupled with denoising or region of interest models. The pivotal decision left to make is how to select the most appropriate VollSeg configuration for your dataset, a question we comprehensively address in our documentation website.
This project provides the napari plugin for VollSeg, a deep learning based 2D and 3D segmentation tool for irregular shaped cells. VollSeg has originally been developed (see papers) for the segmentation of densely packed membrane labelled cells in challenging images with low signal-to-noise ratios. The plugin allows to apply pretrained and custom trained models from within napari.
For detailed demo of the plugin see these videos and a short video about the parameter selection

See the poster presented at BINA 2024 for an overview of the plugins in action
Try out the Virtual I2K 2024 Workshop for an interactive tutorial
Installation
napari-ndev is a pure Python package, and can be installed with pip:
bash
pip install napari-ndev
If napari is currently not installed in your environment, you will also need to include a QtPy backend:
bash
pip install napari-ndev[qtpy-backend]
The easiest way to get started with napari-ndev is to install all the optional dependencies (see note below) with:
bash
pip install napari-ndev[all]

Optional Libraries
napari-ndev is most useful when interacting with some other napari plugins (e.g. napari-assistant) and can read additional filetypes. A few extra BSD3 compatible napari-plugins may be installed with pip:
bash
pip install napari-ndev[extras]
napari-ndev can optionally use GPL-3 licensed libraries to enhance its functionality, but are not required. If you choose to install and use these optional dependencies, you must comply with the GPL-3 license terms. The main functional improvement is from some bioio libraries to support extra image formats, including czi and lif files. These libraries can be installed with pip:
bash
pip install napari-ndev[gpl-extras]
In addition, you may need to install specific bioio readers to support your specific image, such as bioio-czi and bioio-lif (included in [gpl-extras]) or bioio-bioformats.
Development Libraries
For development use the [dev] optional libraries to verify your changes, which includes the [docs] and [testing] optional groups. However, the Github-CI will test pull requests with [testing] only.

The wide breadth of this plugin's scope is only made possible by the amazing libraries and plugins from the python and napari community, especially Robert Haase.

napari-aphid

A plugin to classify aphids by stage of development.

napari-segment-blobs-and-things-with-membranes (nsbatwm)








This napari-plugin is based on scikit-image and allows segmenting nuclei and cells based on fluorescence microscopy images with high intensity in nuclei and/or membranes.
Usage
This plugin populates image processing operations to the Tools menu in napari.
You can recognize them with their suffix (nsbatwm) in brackets.
Furthermore, it can be used from the napari-assistant graphical user interface. 
Therefore, just click the menu Tools > Utilities > Assistant (na) or run naparia from the command line.

You can also call these functions as shown in the demo notebook.
Voronoi-Otsu-Labeling
This algorithm uses Otsu's thresholding method in combination with 
Gaussian blur and a 
Voronoi-Tesselation 
approach to label bright objects such as nuclei in an intensity image. The alogrithm has two sigma parameters which allow
you to fine-tune where objects should be cut (spot_sigma) and how smooth outlines should be (outline_sigma).
This implementation aims to be similar to Voronoi-Otsu-Labeling in clesperanto.

Seeded Watershed
Starting from an image showing high-intensity membranes and a seed-image where objects have been labeled (e.g. using Voronoi-Otsu-Labeling),
objects are labeled that are constrained by the membranes.

Seeded Watershed with mask
If there is additionally a mask image available, one can use the Seeded Watershed with mask, to constraint the flooding 
on a membrane image (1), starting from nuclei (2), limited by a mask image (3) to produce a cell segmentation within the mask (4).

Seeded Watershed using local minima as starting points
Similar to the Seeded Watershed and Voronoi-Otsu-Labeling explained above, you can use this tool to segment an image
showing membranes without an additional image showing nuclei. The two sigma parameters allow to fine tune how close 
objects can be and how precise their boundaries are detected.

Gaussian blur
Applies a Gaussian blur to an
image. This might be useful for denoising, e.g. before applying the Threshold-Otsu method.

Subtract background
Subtracts background using scikit-image's rolling-ball algorithm. 
This might be useful, for example to make intensity of membranes more similar in different regions of an image.

Threshold Otsu
Binarizes an image using scikit-image's threshold Otsu algorithm, also known as 
Otsu's method.

Split touching objects (formerly known as binary watershed).
In case objects stick together after thresholding, this tool might help.
It aims to deliver similar results as ImageJ's watershed implementation.

Connected component labeling
Takes a binary image and produces a label image with all separated objects labeled differently. Under the hood, it uses
scikit-image's label function.

Manual split and merge labels
Split and merge labels in napari manually via the Tools > Utilities menu:

# napari-svetlana








The aim of this plugin is to classify the output of a segmentation algorithm.
The inputs are :

A folder of raw images
Their segmentation masks where each ROI has its own label.

Svetlana can process 2D, 3D and multichannel image. If you want to use it to work on cell images, we strongly
recommend the use of Cellpose for the segmentation part, as it provides excellent quality results and a standard output format
accepted by Svetlana (labels masks). 
If you use this plugin please cite the paper: 
Cazorla, C., Weiss, P., & Morin, R. (2024). Svetlana: a Supervised Segmentation Classifier for Napari.

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation
First install Napari in a Python 3.9 Conda environment following these instructions :
bash
conda create -n svetlana_env python=3.9
conda activate svetlana_env
conda install pip
python -m pip install "napari[all]"==0.4.17
Then, you can install napari_svetlana via pip, or directly from the Napari plugin manager (see Napari documentation):
bash
pip install napari_svetlana
WARNING:
If you have a Cuda compatible GPU on your computer, some computations may be accelerated
using Cupy. Unfortunately, Cupy needs Cudatoolkit to be installed. This library can only be installed via 
Conda while the plugin is a pip plugin, so it must be installed manually for the moment:
bash
conda install cudatoolkit=11.5
Also note that the library (Cucim) that we use to improve these performances, computing morphological operations on GPU
is unfortunately only available for Linux systems. Hence, if you are a Windows user, this installation is not necessary.
Tutorial
Many advanced features are available in Svetlana, such as data augmentation or contextual information reduction, to optimize the performance of your classifier. Thus, we strongly encourage you to
check our Youtube tutorial and
our documentation.
A button called TRY ON DEMO IMAGE is available in the annotation plugin and enables you to apply the YouTube
tutorial to the same test images to learn how to use the plugin. Feel free to try it to test all the features
that Svetlana offers.
Similar Napari plugins
Joel Luethi developed a similar method for objects classification called napari feature classifier.

https://github.com/user-attachments/assets/2af2e1a6-adf9-4d63-a353-e190c4814d83

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.



  Your browser does not support the video tag.

Installation
Conda environment
It is highly recommended to create a dedicated conda environment, by following these few steps:


Install an Anaconda distribution of Python. Note you might need to use an anaconda prompt if you did not add anaconda to the path.


Open an Anaconda prompt as admin to create a new environment using conda. We advice to use python 3.10 and conda 23.10.0, to get conda-libmamba-solver as default solver.


bash
conda create --name cut_detector python=3.10 conda=23.10.0
conda activate cut_detector
Package installation
Once in a dedicated environment, our package can be installed via pip:
bash
pip install cut_detector
Alternatively, you can clone the github repo to access to playground scripts.
bash
git clone https://github.com/15bonte/cut-detector.git
cd cut-detector
pip install -e .
GPU
We highly recommend to use GPU to speed up segmentation. To use your NVIDIA GPU, the first step is to download the dedicated driver from NVIDIA.
Next we need to remove the CPU version of torch:
bash
pip uninstall torch
The GPU version of torch to be installed can be found here. You may choose the CUDA version supported by your GPU, and install it with conda. This package has been developed with the version 11.6, installed with this command:
bash
conda install pytorch==1.12.1 torchvision pytorch-cuda=11.6 -c pytorch -c nvidia
Update
To update cut-detector to the latest version, open an Anaconda prompt and use the following commands:
bash
conda activate cut_detector
pip install cut-detector --upgrade
Definitions
Each detected cell division is labeled with one of the following categories:

NORMAL: Division happening as expected, where (at least) 1 micro-tubule cut is detected.
NO_MID_BODY_DETECTED: Along the cell division, no mid-body was detected on the MKLP1 channel. This category encompasses different cases: the detection may have failed, the mid-body may not express the fluorescence, or this may not actually be a division.
MORE_THAN_TWO_DAUGHTER_TRACKS: Tripolar division. This category encompasses both actual tripolar divisions and wrong identifications of daughter cells (mainly caused by segmentation issues).
NEAR_BORDER: Division close to the border of the image, hence ignored as it is likely to be difficult to detect micro-tubule cuts. A division is classified as NEAR_BORDER as soon as the distance between 1 detected mid-body and the border of the image is less than 20px.
NO_CUT_DETECTED: Division whose mid-body was detected, but with all micro-tubule bridges classified as "No cut". Likely to be at the end of the video, cells dying before the end of division, or cells going out of frame.
TOO_SHORT_CUT: First micro-tubule cut detected before or at 50 minutes. Ignored as this is very unlikely, so it is probably caused by a wrong division detection.

Division movies start at the maximum between:

Mother cell start frame
10 frames before the end of metaphase

Division movies end at the minimum between:

Last frame of any of the daughter cells
Metaphase of any of the daughter cells

blik








blik is a tool for visualising and interacting with cryo-ET and subtomogram averaging data. It leverages the fast, multi-dimensional napari viewer and the scientific python stack.
DISCLAIMER: this package is in development phase. Expect bugs and crashes. Please, report them on the issue tracker and ask if anything is unclear!
Installation
You can either install blik through the napari plugin system, through pip, or get both napari and blik directly with:
bash
pip install "blik[all]"
The [all] qualifier also installs pyqt5 as the napari GUI backend, and a few additional napari plugins that you might find useful in your workflow:
- napari-properties-plotter
- napari-properties-viewer
- napari-label-interpolator
Nightly build
If you'd like the most up to date blik possible, you can install directly from the main branch on github. This also uses napari main, so expect some instability!
pip install "git+https://github.com/brisvag/blik.git@main#egg=blik[all]"
pip install "git+https://github.com/napari/napari.git@main#egg=napari[all]"
Basic Usage
From the command line:
bash
napari -w blik -- /path/to.star /path/to/mrc/files/*
The -w blik is important for proper initialization of all the layers. Always open the main widget open to ensure nothing goes wrong!
blik is just napari. Particles and images are exposed as simple napari layers, which can be analysed and manipulated with simple python, and most importantly other napari plugins.
Widgets
The main widget has a few functions:

experiment: quickly switch to a different experiment id (typically, everything related to an individual tomogram such as volume, particles and segmentations)
new: generate a new segmentation, a new manually-picked set of particles, or a new surface, sphere, or filament picking for segmentation, particle generation or volume resampling.
add to exp: add a layer to the currently selected experiment (just a shorthand for layer.metadata['experiment_id'] = current_exp_id)
slice_thickness: changes the slicing thickness in all dimensions in napari. Images will be averaged over that thickness, and all particles in the slice will be displayed.

There are also widgets for picking surfaces, spheres and filaments:

surface: process a previously picked surface picking layer to generate a surface mesh and distribute particles on it for subtomogram averaging, or resample a tomogram along the surface.
sphere: process a previously picked sphere picking layer to generate a sphere mesh and distribute particles on it for subtomogram averaging.
filament: process a previously picked filament picking layer to generate a filament and distribute particles on it for subtomogram averaging, or resample a tomogram along the filament.

napari-generic-SIMulator






A napari plugin to simulate raw-image stacks of Structured illumination microscopy (SIM). 
The simulation is originally based on the paper GPU-accelerated real-time reconstruction in Python of three-dimensional datasets from structured illumination microscopy with hexagonal patterns by
Hai Gong, Wenjun Guo and Mark A. A. Neil (https://doi.org/10.1098/rsta.2020.0162). 
The calculation can be GPU-accelerated if the CUPY (tested with cupy-cuda11x) is installed. In addition, the TORCH package can complete the acceleration both on CPU if TORCH is installed, and on GPU if TORCH is compiled with the CUDA (tested with torch v1.13.1+cu117) enabled.
Currently applies to:
- conventional 2-beam SIM data with 3 angles and 3 phases
- 3-beam hexagonal SIM data with 7 phases, as described in the paper
- 3-beam hexagonal SIM data with 5 phases at right-angles
- conventional 3-beam 3-D data with 3 angles and 5 phases

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation
You can install napari-generic-SIMulator via pip:
pip install napari-generic-SIMulator

To install latest development version :
pip install git+https://github.com/Meizhu-Liang/napari-generic-SIMulator.git

This plugin is compatible with napari 0.4.17 or above, older versions of napari would show errors in interpolation.
Usage
1) Open napari and create the viewer.
2) Launch two widgets: Point cloud generator and SIM data generator in Plugin.

The two widgets can be tabbed together.
   
3) Choose the type and other parameters of point cloud as a sample in Point cloud generator.
![raw](https://github.com/Meizhu-Liang/napari-generic-SIMulator/raw/main/images/pc.png)

The point cloud can be displayed in three dimensions, and be saved and loaded as .pcd files.

4) Adjust parameters in SIM data generator to simulate a raw image stack.
Apart from basic parameters such as the refractive index, the wavelengths and so on, the z scanning can be either 
   z drift: the conventional SIM (imaging a raw stack at the same z-position) or z step: the drifting case in 
   the papaer mentioned above (imaging only one raw image at a z-position).

The parameters used in the simulation can be saved with the image stack by clicking save tif with tags. Tags (of current or of one stack dragged into napari viewer) can be printed in Python by print tags. 
5) Three-dimensional point spread function (PSF), optical transfer function (OTF) and illumination patterns applied in the simulation can be showed by buttons. Note the all of these correspond the generated raw-image stack, so keep the parameters the same before showing the PSF (or OTF and illumination).

6) The raw image stacks can be then processed by napari-sim-processor (https://www.napari-hub.org/plugins/napari-sim-processor).

napari-feature-classifier






An interactive classifier plugin that allows the user to assign objects in a label image to multiple classes and train a classifier to learn those classes based on a feature dataframe.
Usage

To use the napari-feature-classifier, you need to have a label image and corresponding measurements: as a csv file, loaded to layer.features or in an OME-Zarr Anndata table loaded with another plugin. Your feature measurements need to contain a label column that matches the label objects in the label image.
These interactive classification workflows are well suited to visually define cell types, find mitotic cells in images, do quality control by automatically detecting missegmented cells and other tasks where a user can easily assign objects to groups.
Prepare the label layer:

Load your label layer into napari and add the features measurements to layer.features of the corresponding label layer. You can have multiple label layers with their features open at the same time
To load features from a CSV file: Plugins -> napari-feature-classifier -> CSV Feature Loader, then load the features for the correct label image.
To load features from an OME-Zarr file: Get both the label layer into memory as a normal label layer (not a pyramidal label layer, currently untested) and the corresponding features. If your OME-Zarr file is created by Fractal, you can use this ROI loader plugin.
To load features from anywhere else, load them manually to your label_layer.features


Your feature table should have 2 columns used for indexing (but stored as normal columns in layer.features):
The label column to match the object in the label image
The roi_id column to identify the image you're currently classifying (used when a classifier is trained on multiple label images)



Initialize a classifier:

Start the classifier in napari by going to Plugins -> napari-feature-classifier -> Initialize a Classifier 
Select the features you want to use for the classifier (you need to do the feature selection before initializing. The feature selection can't be changed after initialization anymore). Hold the command key to select multiple features. Feature options are always shown for the features available in the last selected label layer, based on layer.features available features.
(Optional) Give your classes recognizable names (e.g. Mitotic & Interphase, Cell Type a, b and c etc.)


Classify objects:


Make sure you have the label layer selected on which you want to classify
Select the current class with the radio buttons or by pressing 0, 1, 2, etc.
Click on label objects in the viewer to assign them to the currently selected class
Once you have trained enough examples, click "Run Classifier" to run the classifier and have it make a prediction for all objects. Aim for at least a dozen annotations per class, as the classifier divides your annotations 80/20 in training and test sets. 
Once you get predictions, correct mistakes the classifier made and retrain it to improve its performance.
You can save the classifier under a different name or in a different location. Define the new output location and then click Save Classifier (you need to click the Save Classifier button. Just defining the new output path does not save it yet. But every run of the classifier triggers an autosave)


Apply the classifier to additional images:

You can apply a classifier trained on one image to additional label images. Use Plugins -> napari-feature-classifier -> Load Classifier 
Select the classifier (.clf file with the name you gave above) while already having the label images ready (see Prepare the label layer above).
Click Load Classifier, proceed as above.


Export classifier results

To export the training data and the results of the classifier, define an Export Name (full path to an output file or just a filename ending in .csv) where the results of the classifier shall be saved. It defaults to the layer name for the selected layer in the last directory you chose (or the current working directory if none was chosen so far)
Click Export Classifier Result (Just selecting a filename is not enough, you need to click the export button). This will export the predictions for the currently selected layer.
The results of the classifier are save in a csv file. The label is an integer of the label object within that image. The prediction column contains predictions of the classifier for all objects (except those that contained NaNs in their feature data) and the annotation column contains the annotations you made (NaN for unclassified objects, -1 for objects you deselected, 1 - 9 for the classes)


Batch mode result export
(To be updated: Create a new notebook to run batch processing, this is for the older version of the classifier)
There is a simple workflow for the classifier in the examples folder:
- Install jupyter-lab (pip install jupyterlab)
- Open the notebook in jupyter lab (Type jupyter-lab in the terminal when you are in the examples folder)
- Follow the instructions to generate an example dataframe and an example label image
- Use the classifier in napari with this simplified data
Initializing the Annotator
You can use the annotation functionality also independently from the classifier
Start the annotator widget by going to Plugins -> napari-feature-classifier -> Annotator
Select names for your classes. You can name up to 9 classes. Only classes that you give a name will be created upon initialization.
Then click Initialize.

A annotator widget opens. Use the Radio-Buttons to select what class you're annotating (or keybindings for 1-9 for classes, 0 for deselect).
The annotator will always work on the currently selected label layer. While the annotator is open, you can't edit the labels. Restart napari to allow editing of labels again.

The annotations are saved in the layer.features table of the corresponding label layer as an annotations column.

Installation
This plugin is written for the new napari npe2 plugin engine. Thus, it requires napari >= 0.4.13.
Activate your environment where you have napari installed (or install napari using pip install "napari[all]"), then install the classifier plugin:
pip install napari-feature-classifier

The layer.features dataframes have some issues in napari 0.4.17 (see here). They seem to be working again in the nighlty builds. To set up a nightly builds napari env, do the following:
conda create -n classifier-dev-napari-main -c "napari/label/nightly" -c conda-forge napari python=3.10 -y
Similar napari plugins
If you're looking for other classification approaches, apoc by Robert Haase has a pixel classifier in napari and an object classification workflow:
napari-accelerated-pixel-and-object-classification (APOC)
Alternatively, Clément Cazorla has built napari-svetlana, a deep learning based classifier
Release process

Update the version number in src/napari-feature-classifier/init.py
Update the version in setup.cfg
Add a Github release with a new version tag (matching the version set above)
Once tests pass, this should automatically be deployed to pypi
Wait for conda automation to make a PR for an updated conda release (see https://github.com/conda-forge/napari-feature-classifier-feedstock). This can take 1-2 days. Make sure that PR gets merged.

iterseg




napari plugin for iteratively improving a deep learning-based unet-watershed segmentation. 

This napari plugin was generated with Cookiecutter using @napari's cookiecutter-napari-plugin template.

Installation
Install iterseg using pip. Assuming you have python and pip installed (e.g., via miniconda), you can install iterseg with only one line, typed into terminal (MacOS/Linux) or annaconda prompt (Windows). We recomend installing into a new environment as some of our dependencies may not play well in the sandpit with certain versions of packages that may exist in a prexisting one. 
bash
pip install iterseg napari
Opening iterseg
Once iterseg is installed, you can access it through the napari viewer, which you can open from the command line (e.g., terminal (MacOS), anaconda prompt (Windows), git bash (Windows), etc.). To open napari simply type into the command line:
bash
napari
Loading data
Once you've opened napari, you can load image, labels, or shapes data through the load_data widget. to open the widget go to plugins/iterseg/load_data at the top left of your screen (MacOS) or viewer (Windows). 

Once the widget appears at the right of the napari window, enter the name you want to give the data you are loading (this will appear in the layers pannel on the left of the window). Choose the type of layer you want to load (Image, Labels, or Shapes: segmentations are loaded as labels layer). You can load a folder of files or a zarr file using "choose directory" (zarrs are recognised as a folder of files) or you can load a tiff file using "choose file". You can tell the program what the scale of the 3D frames will be in (in the format (z, y, x)).

If you are using a single image file (3D, 4D, 5D - ctzyx) or a directory of 3D images (zyx), for "data type" choose "individual frames". If you are using a directory of 4D images (tzyx) choose "image stacks". If you are loading a file that is 4D or 5D and want to load time points (4D: tzyx, czyx) or channels (5D: ctzyx) as individual layers, select "split channels". 
Segmenting images
You can segment data using the "segment_data" widget, which can be found at plugins/iterseg/segment_data. Once the widget appears, you can choose (1) the image layer you want to segment, (2) the folder into which to save the data, (3) the name you want to give the output file, (4) the type of segmentation to use, (5: optionally) the path to a neural network or configuration file, (6: optionally) a layer produced during training which contains metadata pointing to the trained neual network, (7) chunk size (the size of the neural network input), (8) margin (the margin of overlap between chunks). There is also an optional tickbox for debugging. If this is selected, errors will be easier to identify but you won't be able to interact with the viewer until the segmentation is done. 


Segmented images can be used to more quickly generate ground truth for training, to assess segmentation quality, or for downstream analyses. 
Segmentation algorithms
Affinity U-Net Watershed
The affinity U-net watershed is a feature based instance segmentation algorithm. A trained U-net predicts an edge affinity graph (basically boundaries in the x, y, and z axes), a map of centre points, and a mask that specifies which pixesl belong to objects. The feature map is fed to a modified watershed algorithm. The object centres are used to find seeds for the watershed and the affinity graph is used to find bounaries between objects. If you train a network using iterseg, you can select the outputted network file to segment. Otherwise, if one is not selected, a network we have trained to detect platelets will be used. This might be appropriate for small objects with high anisotropy. 
DoG Blob Segmentation
The DoG blob segmentation uses a difference of Gaussian (DoG) filter to find blob shaped objects. The DoG filter is used to find object seeds, a foreground mask, and is fed to a watershed to label objects. This algorithm cannot be trained but can be configured with a configuration file. An example configuration file can be seen in the example folder in this repository. Please see the Segmentation_config.md file for more details. 
Generating ground truth
We include two tools that are useful for generating ground truth: "save frames" and "ground truth from ROI". 
Save frames
The first tool is "save frames" can be found at plugins/iterseg/save_frames. It enables you to save frames of interest from a  series of segmented images or timeseries. 

Ground truth from ROI
The "ground truth from ROI" tool can be found at plugins/iterseg/ground_truth_from_ROI. This tool enables you to take a small portion of corrected data and place it into a new frame, which can be used for training. The new data can be tiled in the new frame to overrepresent the data in the training data set. At present, the ROI must be selected by adding a shapes layer (added using the icon circled in orange), then adding a rectangle (blue circle).

The rectangle will be used to select a region of the xy-plane. This can be seen in 3D below. 

At present, the entire z stack above and below the rectangle will be used to generate ground truth. We aim to incorporate 3D bounding boxes in the future. If multiple ROIs are selected, multiple new image frames will be made, each with a single ROI. When you generate ground truth from the shapes layer, you are able to select the desired shapes layer, image layer, and labels layer. Additionally, you can choose how many times you want to tile the ROI and how much padding to leave between. Tiling will start at the top right and progress right before moving to the next row. You will also be able to choose the save name and the folder into which to save the data. 

Training a network
iterseg includes a widget for training a u-net for the u-net affinity watershed. The training widget can be found at plugins/iterseg/train_from_viewer. Before training, you will need to load the images and ground truth you want to train from. The images and ground truth should each be a series of 3D frames that are stacked into a layer (we suggest loading from a series of frames in a directory). Once loaded, you are able to select a layer as the ground truth and a layer as the image data. You can tell the program what the scale of the output frames will be (in the format (z, y, x)). You can select what type of center prediction to use (we suggest centredness), what type of prediction to use for the mask, and what extent of affinities you want to train (if n = 1, the network will predict only the direct boundaries between objects in each axis, if greater than 1 the network will still predict the direct boundaires but will also predict where there is a new object n steps away - can be used as collateral learning to enhance training). Affinities extent is developmental. Please submit an issue for any problems. 

For the U-net training, we allow you to choose the learning rate for the ADAM optimiser used to train the network. You can also choose between binary cross entropy loss (BCELoss) and Dice loss (DICELoss). We have found in our data that BCE loss works better. You can also choose how many chunks of data are produced from each frame (n each) and how many epochs you want to train for the training will be done in n_each * n_frames batches with a minibatch size of 1. 
In the future we hope to expand this training widget to enable training other types of networks. Please get involved if you feel you can help with this. 
Assessing segmentations
iterseg includes widgets for assessing and comparing segmentations. If you want to assess segmentation quality, you will need to load a ground truth and a segmentation to assess. Once loaded, you can select the ground truth and segmentation (model segmentation) using the widget found in plugins/iterseg/assess_segmentation. You can select which metrics you want to assess. The metrics we enable are:
- Variation of information (VI): VI is a two part measure. It includes a measure of undersegmentation and oversegmentation. Undersegmentation is a measure of the amount of new information you get from looking at the ground truth if you have already seen the segmentation. It can be interpreted as the proportion of objects that are incorrectly merged. Oversegmentation is a measure of the amount of new information you get from looking at the segmentation if you have already seen the ground truth. It can be interpreted as the proportion of objects that are incorrectly split. For more info please see the scikit-image documentation. 
- Object count difference (OD): Object count difference is simply the difference in number of objects between a ground truth and the assessed segmentation (card(ground truth) - card(segmentation)). 
- Average precision (AP): Average precision  Average precision is a combined measure of how accurate the model is at finding true positive (real) objects (we call this precision) and how many of ground truth real objects it found (this is called recall). The assessment of whether an object is TP, FP, and FN depends on the threashold of overlap between objects. Here we use the intersection of union (IoU), which is the proportion of overlap between the bounding boxes of ground truth and model segemented objects. AP is assessed using different IoU thresholds (from 0.35-0.95). The resultant data will be plotted as IoU by AP. 

Precision = TP / (TP + FP)Recall = TP / (TP + FN). 
Abbreviations: FN, false negative; TP, true positive; FP, false

Basic usage example

NeuroFly packaged 4 napari plugins for image browsing, image segmentation, and data annotation.

Segmentation
NeuroFly supports whole brain image saved in hierarchical data structures(ims, h5, and zarr) in Imaris File Format and small image volumes saved in single-channel tiff format. Here we use a mouse brain in our dataset named z002.zarr.zip as example.
This brain is sparsely labeled, which means only a tiny puny part of neurons are lighted and imaged. To extract these foreground singals, you can use the provided command line interface 'seg'. We provide a default weight trained on images captured by VISoR and fMOST.
seg -i z002.zarr.zip -vis -d z002.db
or use the graphical interface

This process may take about 10 hours depending on your you hardware configuration. When finished, you should see the extracted segments and a database file named z002.db in your working dictionary.

Load image file (z002.zarr.zip) and database file (z002.db), then click refresh panorama button to show the panorama view.

Select one node as start point of annotation
In panorama mode, you can easily identify sparse, bright signals that are promising for reconstruction. The silde bars 'short segs filter', 'length thres', and 'point size' can be adjusted to hide noise and short segments. 
If you can clearly identify foreground segments, click on one of the conspicuous segments to select it as start point of annotation. Once selected, the id of picked node will be displayed at node selection. Then click 'switch mode' to switch to labeling mode, and the tasks will be generated automatically.
Task generation
Given a selected node, task generator analyses its connected component and extract all unchecked terminal nodes. The tasks are designed very simple: Connect the center node with the surrounding nodes if there should be an edge. The criterion is whether the edge aligns well with the imaged neuron fibers.

Node operations

In each task, a center node and nearby segments are rendered, you can add/remove nodes and edges to get a reasonable local structure.
Left click on nodes to add/remove an edge between it and the center node

Right click to remove a node

Press 'g' or use left panel to switch to 'image' layer, then right click to add points

Use dropdown selection in right panel to add type label for center node.

Deconvolution
Press 'i' or click on 'deconvolution' to deconvolve the image

Proofreading
If you find something wrong when labeling, for example, two somas are connected together. You can use proofreading mode to check the neuron branch by branch.

Performance
NeuroFly supports rendering of more than ten million points. (tested on M3 Macbook Air and RTX 3090 workstation)

Export as swc file
Switch to panorama mode, adjust 'length_thres' to filter out short segments and keep only complete neurons. Then press 'export swc files', each neuron will be saved as one .swc file in your working dictionary.

napari-assistant








The napari-assistant is a napari meta-plugin for building image processing workflows. 
Usage
After installing one or more napari plugins that use the napari-assistant as user interface, you can start it from the 
menu Tools > Utilities > Assistant (na) or run naparia from the command line. 
By clicking on the buttons in the assistant, you can setup a workflow for processing the images.

While setting up your workflow, you can at any point select a layer from the layer list (1) and change the parameters of
the corresponding operation (2). The layer will update when you change parameters and also all subsequent operations. 
You can also vary which operation is applied to the image (3). Also make sure the right input image layer is selected (4).

Saving and loading workflows
You can also save and load workflows to disk. 

After loading a workflow, make sure that the right input images are selected.
Code generation
The napari-assistant allows exporting the given workflow as Python script and Jupyter Notebook. 

Furthermore, if you have the napari-script-editor installed,
you can also send the current workflow as code to the script editor from the same menu.

Plugin generation
There is also a Napari plugin generator available. Check out its documentation to learn how napari-assistant compatible plugins can be generated directly from within the assistant.
Installation
It is recommended to install the napari-assistant via one of the plugins that use it as graphical user interface.
You find a complete list of plugins that use the assistant on the napari-hub.
Multiple of these plugins come bundled when installing devbio-napari.
Note: This plugin is not compatible with napari 0.6.0 and later.
For developers
If you want to make your napari-plugin accessible from the napari-assistant, consider programming functions with a simple 
interface that consume images, labels, integers, floats and strings. Annotate input and return types, e.g. like this:
```python
def example_function_widget(image: "napari.types.ImageData") -> "napari.types.LabelsData":
    from skimage.filters import threshold_otsu
    binary_image = image > threshold_otsu(image)
from skimage.measure import label
return label(binary_image)

```
Furthermore, please add your function to the napari.yaml which uses npe2:
name: napari-npe2-test
display_name: napari-npe2-test
contributions:
  commands: 
    - id: napari-npe2-test.make_magic_widget
      python_name: napari_npe2_test._widget:example_magic_widget
      title: Make example magic widget
  widgets:
    - command: napari-npe2-test.make_magic_widget
      display_name: Segmentation / labeling > Otsu Labeling (nnpe2t)
To put it in the right button within the napari-assistant, please use one of the following prefixes for the display_name:
* Filtering / noise removal >
* Filtering / background removal >
* Filtering >
* Image math >
* Transform >
* Projection >
* Segmentation / binarization >
* Segmentation / labeling >
* Segmentation post-processing >
* Measurement >
* Label neighbor filters >
* Label filters >
* Visualization >
You find a fully functional example here.
Last but not least, to make your napari-plugin is listed in the napari-hub when searching for "napari-assistant", make sure
you mention it in your readme.

napari-kld




napari-kld is a napari plugin that implements kernel learning deconvolution algrotihm.
Kernel Learning Deconvolution (KLD)
KLD is a rapid deconvolution algorithm for fluorescence microscopic image, which learns the forward and backward kernels in Richardson-Lucy Deconvolution (RLD) from paired low-resolution (LR) and high-resolution (HR) images.
It only requires one sample to training the model, and two iterations to achieve a superior deconvolution performance compared to RLD and its variants using unmatched backward projection.
*This napari plugin was generated with copier using the napari-plugin-template.
Installation
You must install napari firstly and then install napari-kld.
Install napari
You can download the napari bundled app for a simple installation via https://napari.org/stable/tutorials/fundamentals/quick_start.html#installation.
Or, you can install napari with Python using pip:
conda create -y -n napari-env -c conda-forge python=3.10
conda activate napari-env
python -m pip install 'napari[all]'
Refer to https://napari.org/stable/tutorials/fundamentals/quick_start.html#installation.
Install napari-kld
You can install napari-kld plugin with napari:
Plugins > Install/Uninstall Plugins… > [search napari-kld] > install.
Or you can install napari-kld via pip:
pip install napari-kld

Instruction
This plugin includes two part:


RL Deconvolution : Conventional RLD algorithm using different type of backward kernels (including matched backward kernel [Traditional] and unmatched backward kernels [Guassian, Butterworth, Wiener-Butterworth (WB)]). The forward kernel, i.e., point spread function (PSF), is required.


KL Deconvolution : KLD using learned forward/backward kernels.


You can download the "test" folder  at https://github.com/qiqi-lu/kernel-learning-deconvolution for testing, which save some 2D/3D images used for training and testing.
RL Deconvolution
The conventional RLD using different type of backward kernels.


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > RL Deconvolution


Load input low-resolution (LR) image: File > Open File(s) > [choose the image to be deconvolved] > [the image will appear in the layer list of napari], such as the simulated image "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/train/raw/0.tif".


Choose the name of loaded image in Input RAW data, such as "0".


Press Choose to choose a PSF correspongding to the loaded image, such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/train/psf.tif".


Choose the type of backward kernel in Method combo box:

Traditional : the backward kernel is just the flip of forward kernel (i.e., PSF).
Guassian : Guassian-shaped backward kernel, thw FWHM of which is same as the forward kernel.
Butterworth : Butterworth-shaped backward kernel, which is constructed using Butterworth filter.
WB : WB-shaped backward kernel, which is constructed by combining Wiener and Butterworth filter.



Set the number of RL iterations Iterations and parameters of backward kernel*.


Press run button to do deconvolution.


Wait the progress bar to reach 100%.


The output deconved image will appear in the layer list named as {name of input image}_deconv_{Method}_iter_{Iterations}, such as "0_deconv_traditional_iter_30".


*The adjustment of parameters of backward kernels should refer to the paper : Guo, M. et al. Rapid image deconvolution and multiview fusion for optical microscopy. Nat Biotechnol 38, 1337–1346 (2020).
KL Deconvolution
Training data preparation
The data used for training must be prepared in a folder consisting of:

A folder named "gt" (optional) , such as "test/data/real/2D/train/gt", which saves all the GT images (only support .tif file).
A folder named "raw", such as "test/data/real/2D/train/raw", which saves all the LR images (only support .tif file). The file names must be the same as those in "gt" folder.
A file named "train.txt", such as "test/data/real/2D/train/train.txt", which saves the name of each image in "gt"/"raw" filder in each line.

When yuo have paired LR image and HR image
When we have paired LR image and HR image, we can treat LR image as raw input and HR image as ground truth (GT). We can first learn the forward kernel and then learn the backward kernel in a supervised strategy.
Training of Forward Projection
Train the forward projection to learn forward kernel.


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > KL Deconvolution


Choose Training tab.


Choose Data Directory, such as "test/data/real/2D/train". Then the dimention of training data will show in the Dimension box.


Choose Output Directory, such as "test/data/real/2D".


PSF Directory is not required as the PSF is unknown.


If the raw input and GT image have different intensity, please check the Preprocess check box, which will rescale the input and GT images to have the same intensity. Here, do not check.


In the Forward Projection box, set the parameters of training:

Epoch : number of epochs of training.
Batch Size : batch size of training data used during training.
Kernel Size (z, xy) : the size of forward kernel to learned.
Optimizer : the optimization algorithm. Default: Adam.
Learning Rate : learning rate of training.
Decay Step ： the decay step of learning rate. Note: 0 for no decay.
Decay Rate : the decay rate of learning rate.



Press run button. You can press the stop button to end the training.


Wait the progress bar to reach 100% and training finished.


After the training of forward projection, the results will be save in the /checkpoints folder in Output Directory, the model was named as forward_bs_{batch size}_lr_{learning rate}_ks_{kernel size (z)}_{kernel size (xy)}, such as "test/data/real/2D/checkpoints/forward_bs_1_lr_0.001_ks_1_31", which consists of:
- a log folder saved the Tensorboard log, which can be opened with Tensorboard.
- many model checkpoints, named as epoch_{epoch}.pt.
- a parameters.json file saving the parameters used to training the model.
Training of Backward Projection
After training of forward projeciton, we can freeze the forward projeciton and then train the backward projeciton.


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > KL Deconvolution


Choose Training tab.


Choose Data Directory, such as "test/data/2D/real/train". Then the dimention of training data will show in the Dimension box.


Choose Output Directory, such as "test/data/2D/real".


PSF Directory is no required as the PSF is unknown.


If the raw input and GT image have different intensity, please check the Preprocess check box, which will rescale the input and GT images to have the same intensity. Here, do not check.


In the Backward Projeciton box, set parameters for the trianing of backward projeciton.

Training strategy : supervised training or self-supervised training. Here, set as supervised, as we have the GT images. When choosing the self-supervised mode, a PSF is required.
Iterations (RL) : The number of iterations of RL iterative procedure. Default: 2.
Epoch : The number fo epochs used to traing the model.
Batch Size : The batch size used to training the model.
Kernel Size (z, xy): The size of backward kernel, x and y have the same size.
FP directory : the directory of the pre-trained forward projeciton model, such as "test/data/real/2D/checkpoints/forward_bs_1_lr_0.001_ks_1_31/epoch_500_final.pt" (commonly the model labeled with "_final" is used).
Optimizer : Optimization algorithm. Default: Adam.
Learning Rate : The learning rate used to trianing the model.
Decay Step : the decay step of learning rate.
Decay Rate : the decay rate of learning rate.



Press run button. You can press the stop button to end the training.


Wait the progress bar to reach 100% and then the training finishes.


When the training finishes, the results will be save in the /checkpoints folder in Output Directory, the model was named as backward_bs_{batch size}_lr_{learning rate}_iter_{num of RL iterations}_ks_{kernel size (z)}_{kernel size (xy)}, such as "test/data/real/2D/checkpoints/backward_bs_1_lr_1e-05_iter_2_ks_1_31", which consists of:

a log folder saved the Tensorboard log, which can be opened with Tensorboard.
many model checkpoints, named as epoch_{epoch}.pt.
a parameters.json file saving the parameters used to training the model.

Now we get the learned forward projection and backward projection.
Next, we can use them to do Prediction.
When you only have a PSF
When you only have a PSF to do deconvolution, you can train the model using simulated data following the below steps:

Generate simulaiton data.
Train the model under supervised mode.
Apply the trained model on real data.

Simulation data generation


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > KL Deconvolution


Choose Simulation tab.


Choose the Output Directory of the generated simulation data, such as "test\data\simulation".


Choose the PSF Directory (only support 2D/3D PSF file save as .tif, axes = (y, x) or (z, y, x)), such as "test\data\simulation\psf.tif".


Adjust the parameters as needed.

Image Shape : the shape of simulated image, when z=1, 2D image will be generated.
PSF Crop : when the input PSF is too large, you can crop the PSF to acuqire a smaller PSF. All the PSF will be converted to have an odd shape and normalized.
Num of Simulations : number of generated images.
Gaussian (std) : the standard deviation (std) of Gaussian noise added in the generated LR images. The mean of Gaussian noise = 0. Default: 0 (i.e., without gaussian noise).
Poisson : whether to add Poisson noise, if True, make the Enable checked.
Ratio : a ratio factor multiplied on GT image to control the level of Poisson noise, thus the simulated raw input LR image RAW can be expressed as:

$$ RAW = Possion((GT \cdot Ratio)\times PSF) + Gaussian $$

Scale Factor : downsampling scale factor. Default: 1.



Press run button.


Wait the progress bar to reach 100%.


The generated simulation data will be save in Output directory, named as "data_{shape_z}_{shape_y}_{shape_x}_gauss_{std of Gaussian noise}_poiss_{whether to add Poisson noise}_ratio_{Ratio}", such as: "test\data\simulation\data_128_128_128_gauss_0.0_poiss_0_ratio_1.0\train"

"data\train\gt" saves the GT images which consist of structures with various shapes*.
"data\train\raw" saves the RAW images with blur and noise.
"data\train\parameters.json" is a dictionary of parameters used to generate the simulation data.
"data\train\psf.tif" is the PSF used in the simulation data generation (as the original PSF may be cropped).
"data\train\train.txt save all the image used to train the model.

After you generate simulation data, you can use them to train the model.
*the code was refered to the paper: Li, Y. et al. Incorporating the image formation process into deep learning improves network performance. Nat Methods 19, 1427–1437 (2022).
You may need to adjust the noise level in the image accordding to the real acuqired data.
Training with known PSF and simulated data
The simulated data should be those generated using the known PSF.


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > KL Deconvolution


Choose Training tab.


Choose Data Directory, such as test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/train", which saves the data used to train the model in should include:

A gt folder saves the GT images
A raw folder save the raw input LR images with the same file name as GT images
A train.txt file saves all the file names used to train the model (does not need to list all the files in gt/raw folder but at least one).



Choose a Output Directory to save the model checkpoints, such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0".


Choose PSF Directory of the PSF corresponding to the data, such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/train/psf.tif". Then the Forward Projection group box will be invisible as we do not need to learn the forward kernel when we know the PSF. Just use the PSF as the forward kernel.


If the raw input and GT image have different intensity, please check the Preprocess check box, which will rescale the input and GT images to have the same intensity. Here, do not check.


Then set parameters to learn the backward kernel.

Training Strategy : supervised training or self-supervised training. Here, set as supervised, as we have the GT images.
Iterations (RL) : the number of iterations of RL iteration procedure. Default: 2.
Epoch : the number fo epochs used to traing the model.
Batch Size : the batch size used to training the model.
Kernel Size (z, xy): the size of backward kernel, x and y directions have the same size.
FP Directory : the directory of the forward projeciton model. Here, it is disabled as the PSF is known.
Optimizer : Optimization algorithm. Default: Adam.
Learning Rate : the learning rate used to trianing the model.
Decay Step : the decay step of learning rate.
Decay Rate : the decay rate of learning rate.



Press run button. You can press the stop button to end the training.


Wait the progress bar to reach 100% and the training finishes.


When the training finishes, a checkpoints folder will be created in Output Directory such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/checkpoints".
The models is save in /checkpoints folder, which is named as "backward_bs_{batch size}_lr_{learning rate}_iter_{num of RL iterations}_ks_{kernel size (z)}_{kernel size (xy)}", such as "/checkpoints/backward_bs_1_lr_1e-06_iter_2_ks_1_31", consists of:

A log folder saved the Tensorboard log, which can be open with Tensorboard.
Many model checkpoints, named as epoch_{epoch}.pt.
A parameters.json file saving the parameters used to training the model.

When you only have LR image and corresponding PSF
When we only have LR image and its PSF, we can traing the backward projection through supervised training using simulation data as introduced above. The plugin also provide an alternative self-supervised training stratergy to learn the backward kernel.


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > KL Deconvolution


Choose Training tab.


Choose Data Directory, such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/train".


choose Output Directory, such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0".


Choose PSF Directory, such as "test/data/simulation/data_128_128_128_gauss_0.0_poiss_0_ratio_1.0/train/psf.tif" then the Forward Projection box will be invisiable.


As there is no GT image, preprocessing is not needed. Do not check Preprocess check box.


In the Backward Projeciton box, set parameters for the trianing of backward projeciton.

Training strategy : supervised training or self-supervised training. Set as self-supervised, as we do not have the GT images.
Iterations (RL) : the number of iterations of RL iteration procedure. Default: 2.
Epoch : the number fo epochs used to traing the model.
Batch Size : the batch size used to training the model.
Kernel Size (z, xy): the size of backward kernel, x and y directions have the same size.
FP Directory : the directory of the forward projeciton model. Here, it is disabled as the PSF is known.
Optimizer : Optimization algorithm. Default: Adam.
Learning Rate : the learning rate used to trianing the model.
Decay Step : the decay step of learning rate.
Decay Rate : the decay rate of learning rate.



Press run button. You can press the stop button to end the training.


Wait the progress bar to reach 100% and training finishes.


When the training finishes, the results will be save in the /checkpoints folder in Output Directory, the model was named as backward_bs_{batch size}_lr_{learning rate}_iter_{num of RL iterations}_ks_{kernel size (z)}_{kernel size (xy)}_ss, such as "/checkpoints/backward_bs_1_lr_1e-05_iter_2_ks_31_31_ss", which consists of:

a log folder saved the Tensorboard log, which can be opened with Tensorboard.
many model checkpoints, named as epoch_{epoch}.pt.
a parameters.json file saving the parameters used to training the model.

The performance of self-supervised learning may be inferior to supervised learning according to our experiments.
Prediction
Use the learned forward/backward kernel to do deconvolution.


Open napari and load napari-kld plugin: Plugins > Kernel Learning Deconvolution > KL Deconvolution


Choose Prediction tab.


Load raw input low-resolution image through napari: File > Open File(s) > [choose the image to be deconvolved] > [the image will appear in the layer list of napari], such as "test/data/real/2D/test/raw/2.tif".


Choose the loaded image in Input RAW data box, e.g., 2.


If the PSF is known, choose the PSF directory.


If the PSF is unknown, choose the Forward Projection directory, such as "test/data/real/2D/checkpoints/forward_bs_1_lr_0.001_ks_1_31/epoch_500_final.pt" (commonly the model labeled with "_final" is used). If both the directories of PSF and Forward Projeciton is choosen, KLD will directly use the PSF selected.


Choose the Backward Projeciton directory, such as "test/data/real/2D/checkpoints/backward_bs_1_lr_1e-05_iter_2_ks_1_31/epoch_1000_final.pt"  (commonly the model labeled with "_final" is used).


Set the number of RL iterations at Iterations (RL). Default: 2.


Press run to do deconvolution.


Wait the progress bar to reach 100%.


The deconvolved image will be directly shown in the layer list of napari, named as "{input data name}_deconvo_iter_{number of RL iterations}", e.g., "16_deconv_iter_2". You can save it as needed.
Others
The log tab print the message during running.
Press clean button will clean all the text in the log box.
Notice


Currently, the plugin is runned on CPU. We have tried to run the training on GPU, but the training time did not decrease (maybe it is because the FFT-based covnlution was not optimized on GPU). We are trying to make improvements.


The training time may be very long if we set the kernel size or the number of epoches too large, especially for 3D images. Besides, it also depends on the  computation capability of your device.
