MNE is a community-driven software package designed for processing electroencephalography (EEG) and magnetoencephalography (MEG) data providing comprehensive tools and workflows for (among other things):
MNE includes a comprehensive Python package supplemented by tools compiled from C code for the LINUX and Mac OSX operating systems, as well as a MATLAB toolbox.
