A module for estimating Hemodynamical Response Function from functional MRI data

Project description

This is a Python package that implements several methods for the joint estimation of HRF and activation patterns (aka beta-map) from fMRI (BOLD) signal.

If you use this software, please cite (at least) one of the following papers

“Data-driven HRF estimation for encoding and decoding models”, Fabian Pedregosa, Michael Eickenberg, Philippe Ciuciu, Bertrand Thirion and Alexandre Gramfort. URL:

“HRF estimation improves sensitivity of fMRI encoding and decoding models”, Fabian Pedregosa, Michael Eickenberg, Bertrand Thirion and Alexandre Gramfort. URL:


hrf_estimation is a pure Python package and can be installed through the Python Package Index (PYPI):

pip install -U hrf_estimation

You can also download the source code from the PYPI website or get the latest sources from github
