a napari plugin for anatomical segmentation of general cellular images

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

The plugin code was written by Carsen Stringer, and the cellpose code was written by Carsen Stringer and Marius Pachitariu. To learn about Cellpose, read the paper or watch this talk.

For support with the plugin, please open an issue. For support with cellpose, please open an issue on the cellpose repo.

Installation

Install an Anaconda distribution of Python -- Choose Python 3 and your operating system. Note you might need to use an anaconda prompt if you did not add anaconda to the path.

Install napari with pip: pip install napari[all]. Then install cellpose-napari via [pip]:

pip install cellpose-napari

Or install the plugin inside napari in the plugin window.

If install fails in your base environment, create a new environment:

Download the environment.yml file from the repository. You can do this by cloning the repository, or copy-pasting the text from the file into a text document on your local computer.
Open an anaconda prompt / command prompt with conda for python 3 in the path
Change directories to where the environment.yml is and run conda env create -f environment.yml
To activate this new environment, run conda activate cellpose_napari
You should see (cellpose_napari) on the left side of the terminal line.

If you have issues with cellpose installation, see the cellpose docs for more details, and then if the suggestions fail, open an issue.

Upgrading software

You can upgrade the plugin with

pip install cellpose-napari --upgrade

and you can upgrade cellpose with

pip install cellpose --upgrade

GPU version (CUDA) on Windows or Linux

If you plan on running many images, you may want to install a GPU version of torch (if it isn't already installed).

Before installing the GPU version, remove the CPU version:

pip uninstall torch

Follow the instructions here to determine what version to install. The Anaconda install is recommended along with CUDA version 10.2. For instance this command will install the 10.2 version on Linux and Windows (note the torchvision and torchaudio commands are removed because cellpose doesn't require them):

conda install pytorch cudatoolkit=10.2 -c pytorch

When upgrading GPU Cellpose in the future, you will want to ignore dependencies (to ensure that the pip version of torch does not install):

pip install --no-deps cellpose --upgrade

Installation of github version

Follow steps from above to install the dependencies. In the github repository, run pip install -e . and the github version will be installed. If you want to go back to the pip version of cellpose-napari, then say pip install cellpose-napari.

Running the software

Open napari with the cellpose-napari dock widget open

napari -w cellpose-napari

There is sample data in the File menu, or get started with your own images!
