EEGLAB

EEGLAB is a toolbox of 250 routines for analyzing and visualizing event-related EEG (or MEG) brain data. A graphic user interface allows users to explore their data interactively, while global data, event and channel location structures, plus a command history
mechanism, ease the transition to writing custom analysis scripts. An extensive .html tutorial and help messages allow users to learn all parts of the system. MATLAB and binary routines for performing infomax and extended-infomax ICA are included, as is the sample EEG data set used throughout the tutorial.
