This repository contains the software related to the publication ToFFi - Toolbox for frequency-based fingerprinting of brain signals, published 24th April 2023 in Neurocomputing journal, by Michał Konrad Komorowski (@micholeodon) from Neurocognitive Laboratory at Nicolaus Copernicus University, Torun, Poland, and his collaborators.
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.
- MATLAB (version R2021a or newer)
- FieldTrip toolbox (version 20210816 or newer)
The following toolboxes need to be installed alongside MATLAB:
- Signal Processing Toolbox,
- Statistics and Machine Learning Toolbox,
- Parallel Computing Toolbox.
- Clone, or download this repository as a
.zipfile and unpack. - The ToFFi toolbox is ready to use.
The full documentation of the ToFFi Toolbox can be found here.
