mtrf 2.1.2

Tools for modeling brain responses using (multivariate)temporal response functions.

mTRFpy - multivariate linear modeling

This is an adaptation of the matlab mTRF-toolbox using only basic Python and Numpy. It aims to implement the same methods as the original toolbox and advance them. This documentation provides tutorial-like demonstrations of the core functionalities like model fitting, visualization and optimization as well as a comprehensive reference documentation.

News

• [2025.10.13] 🔧 Version 2.1.1 has been released for fixing the bug when fs is provided as a native int. A native int causes the array-api-compat.floor/ceil throw the error that fs doesn't have the attribute 'dtype'.
• [2025.10.11] 🚀 Version 2.1.0 has been released! mTRFpy is now compatible with the Array API standard through array-api-compat. ✨ New feature: Support for fitting a separate regularization parameter for each output channel.

Installation

You can get the stable release from PyPI:

    pip install mtrf 

Or get the latest version from this repo:

    pip install git+https://github.com/powerfulbean/mTRFpy.git

While mTRFpy only depends on numpy, matplotlib is an optional dependency used to visualize models. It can also be installed via pip:

    pip install matplotlib

We also provide an optional interface to MNE-Python so it might be useful to install mne as well.
