matisse 0.2.0

Modern and modular MATISSE interferometric data-reduction pipeline interface

Modern and modular MATISSE interferometric data-reduction pipeline python interface. Developed by the MATISSE Consortium. It provides a user-friendly command-line interface (matisse) as well as backward compatibility with the original consortium scripts located in legacy/.

🚀 Installation (Users)

Recommended for end-users who only need to use the pipeline.

This project uses uv to manage environments and dependencies. It’s fully compatible with pip but much faster and simpler to use.

1️⃣ Install uv

On Linux / macOS:

curl -LsSf https://astral.sh/uv/install.sh | sh

2️⃣ Create and activate a virtual environment

uv venv
source .venv/bin/activate

3️⃣ Install the package

uv pip install matisse

🧑‍💻 Developer installation

For contributors or developers working on the pipeline codebase.

1️⃣ Clone the repository

git clone https://github.com/Matisse-Consortium/matisse-pipeline.git
cd matisse-pipeline

2️⃣ Install in editable mode with dev dependencies

uv pip install -e . --group test --group typecheck

This installs:

• pytest, ruff, and pre-commit for testing and linting
• mypy and types-termcolor for type checking

3️⃣ Run tests

uv run pytest

4️⃣ Lint and type check

uv run ruff check src/
uv run mypy src/

🧰 Legacy Scripts Compatibility

The original MATISSE reduction tools (mat_autoPipeline.py, etc.) are preserved in the legacy/ folder for full backward compatibility. They can be accessed by adding the legacy path to your environment:

export PATH="$PATH:$(python -c 'import matisse, pathlib; print(pathlib.Path(matisse.__file__).parent / "legacy")')"

You can add this line to your ~/.zshrc or ~/.bashrc to make it persistent.

Once exported, the commands will be available globally, e.g.:

mat_autoPipeline.py --dirCalib=.
