Nilearn Extra

Nilearn Extra is a small add-on for Nilearn (Statistics for NeuroImaging in Python). It currently adds some functional connectivity measures to the mix.

Installation

pip install nilearn-extra

Usage

- from nilearn.connectome import ConnectivityMeasure
+ from nilearn_extra.connectome import ConnectivityMeasure

Extra Connectivity Matrices

Nilearn Extra supports two additional connectivity matrices:

• Chatterjee XiCorr (kind="chatterjee") is a new correlation coefficient as described in Chatterjee (2019).
• Transfer Entropy (kind="transfer entropy") between regions X and Y is amount of uncertainty reduced in Y by knowing the past values of X. Transfer entropy is an asymmetric measure, so is the connectivity matrix.

Optional Dependencies

# transfer entropy connectivity requires `pyinform` package.
pip install pyinform
