T-MIDAS was created with a focus on the reproducibility of batch image processing and quantification
- Batch processing pipelines for image format conversion, preprocessing, segmentation, ROI analysis
- Executable with a simple, text-based user interface
- Runs on any low-grade workstation with a single GPU
- Modular and simple codebase with few dependencies for easy maintenance
- Supported imaging modalities: Confocal microscopy, slidescanner, multicolor, brightfield
- Logs all your workflows and your parameter choices to a simple CSV
- You can fork this repository to adapt the batch processing scripts to your own image analysis workflows
- Quick installation
T-MIDAS is built on established image processing libraries such as scikit-image, py-clesperanto and CuPy.
All dependencies are listed here.

A prerequisite is the Conda package and environment management system.
The minimal Conda installer miniforge is preferable for its simplicity and speed.
After installing miniforge, you can use mamba in the Linux terminal. Now you need to download the T-MIDAS repository either using
git clone https://github.com/MercaderLabAnatomy/T-MIDAS.git
or by downloading and unpacking the ZIP. In your terminal, change directory to the T-MIDAS folder and type
python ./scripts/install_dependencies.py
This will create the T-MIDAS environment and install all its dependencies.
To start the text-based user interface in your terminal, change directory to the T-MIDAS folder and type
python ./scripts/user_welcome.py
