Framework of Information Theory for Electrophysiological data and Statistics

Project description


FRITES = Framework for Information Theoretical analysis of Electrophysiological data and Statistics

Frites is a python package for analyzing neurophysiological brain data (i.e M/EEG, sEEG / iEEG / ECoG). The package is entirely based on information theoretic measures (such as mutual information (MI)) in order to perform analysis such as :

  • “Correlation like” (I(c; c) = MI between two continuous variables)
  • “Machine-learning like” (I(c; d) = MI between a continuous and a discrete variable)
  • “Partial correlation like” (I(c; c | d) = MI between two continuous variables and removing the influence of a discrete one)
  • Information-transfer about a specific feature

For a comprehensive (and extensive) review, see the paper of Robin AA Ince A statistical framework for neuroimaging data analysis based on mutual information estimated via a gaussian copula.

Frites also comes with embedded statistics which support fixed and random-effect analysis in combination with inferences either at the single time-point level or at the temporal cluster level.

Take a look at the online documentation and examples to start analyzing your data with Frites :



The main dependencies of Frites are :

In addition to the main dependencies, here’s the list of additional packages that you might need :

  • Pandas and Xarray : additional output types
  • Numba : speed computations of some functions

User installation

Frites can be installed (and/or updated) via pip with the following command :

pip install -U frites

Developer installation

For developers, you can install frites in develop mode with the following commands :

git clone
cd frites
python develop
