MyoQuant🔬: a tool to automatically quantify pathological features in muscle fiber histology images

MyoQuant🔬 is a command-line tool to automatically quantify pathological features in muscle fiber histology images.
It is built using CellPose, Stardist, custom neural-network models and image analysis techniques to automatically analyze myopathy histology images. Currently MyoQuant is capable of quantifying centralization of nuclei in muscle fiber with HE staining and anomaly in the mitochondria distribution in muscle fibers with SDH staining.

An online demo with a web interface is available at https://lbgi.fr/MyoQuant/. This project is free and open-source under the AGPL license, feel free to fork and contribute to the development.

Warning: This tool is still in early phases and active development.

How to install

Installing from PyPi (Preferred)

MyoQuant package is officially available on PyPi (pip) repository. https://pypi.org/project/myoquant/

Using pip, you can simply install MyoQuant in a python environment with a simple: pip install myoquant

Installing from sources (Developers)

1. Clone this repository using git clone https://github.com/lambda-science/MyoQuant.git
2. Create a virtual environment by using python -m venv .venv
3. Activate the venv by using source .venv/bin/activate
4. Install MyoQuant by using pip install -e .

How to Use

To use the command-line tool, first activate your venv in which MyoQuant is installed: source .venv/bin/activate
Then you can perform SDH or HE analysis. You can use the command myoquant --help to list available commands.

💡Full command documentation is avaliable here: CLI Documentation

• For SDH Image Analysis the command is:
  myoquant sdh-analysis IMAGE_PATH
  Don't forget to run myoquant sdh-analysis --help for information about options.
• For HE Image Analysis the command is:
  myoquant he-analysis IMAGE_PATH
  Don't forget to run myoquant he-analysis --help for information about options.

If you're running into an issue such as myoquant: command not found please check if you activated your virtual environment with the package installed. And also you can try to run it with the full command: python -m myoquant sdh-analysis --help

Advanced information

Model path and manual download

For the SDH Analysis our custom model will be downloaded and placed inside the myoquant package directory. You can also download it manually here: https://lbgi.fr/~meyer/SDH_models/model.h5 and then you can place it in the directory of your choice and provide the path to the model file using:
myoquant sdh-analysis IMAGE_PATH --model_path /path/to/model.h5
