ToFFi Toolbox

This repository contains "before peer review" version of the software related to the preprint of the publication ToFFi - Toolbox for Frequency-based Fingerprinting of Brain Signals (arXiv:2110.09919) by Michał Konrad Komorowski (@micholeodon) from Neurocognitive Laboratory at Nicolaus Copernicus University, Torun, Poland, and his collaborators.

Abstract

Spectral Fingerprints (SFs) are unique power spectra signatures of human brain regions of interest (ROIs, Keitel & Gross, 2016). SFs allow for accurate ROI identification and can serve as biomarkers of differences exhibited by non-neurotypical groups. At present, there are no open-source, versatile tools to perform Spectral Fingerprinting.

We have filled this gap by creating a modular, highly-configurable MATLAB Toolbox for Frequency-based Fingerprinting (ToFFi). It can transform MEG/EEG signals into unique spectral representations using ROIs provided by anatomical (AAL, Desikan-Killiany), functional (Schaefer), or other custom volumetric brain parcellations. Toolbox design supports reproducibility and parallel computations.
