A multi-modal, multi-variate pattern analysis (MVPA) toolbox in Matlab / GNU Octave for cognitive neuroscientists.
CoSMoMVPA¶
State-of-the art, yet simple to use MVPA implementations.
Runs on the Matlab and GNU Octave platform, on MS Windows, OSX, and GNU/Linux.
Handles fMRI volumetric, fMRI surface-based, and MEEG data through a uniform data structure.
Support for a wide range of data formats.
Searchlights in the volume, on the surface, over sensors, time bins, and frequency bands.
Multiple-comparison correction using Threshold-Free Cluster Enhancement Monte Carlo simulations.
Extensive documentation, including a variety of runnable scripts and implementation exercises (with solutions).
Is Free/Open Source Software (MIT License), see http://github.com/CoSMoMVPA/CoSMoMVPA.
