EEGLAB	Matlab graphic user interface environment for electrophysiological data analysis incorporating the ICA/EEG toolbox (Makeig et al.) developed at CNL / The Salk Institute, 1997-2001. Released 11/2002- as eeglab (Delorme, Makeig, et al.) at the Swartz Center for Computational Neuroscience, Institute for Neural Computation, University of California San Diego (http://sccn.ucsd.edu/). User feedback welcome: email eeglab@sccn.ucsd.edu
Authors:	Arnaud Delorme and Scott Makeig, with substantial contributions from Colin Humphries, Sigurd Enghoff, Tzyy-Ping Jung, plus contributions from Tony Bell, Te-Won Lee, Luca Finelli and many other contributors.
Description:	eeglab is Matlab-based software for processing continuous or event-related EEG or other physiological data. It is designed for use by both novice and expert Matlab users. In normal use, the eeglab graphic interface calls graphic functions via pop-up function windows. The eeglab history mechanism can save the resulting Matlab calls to disk for later incorporation into Matlab scripts. A single data structure ('EEG') containing all dataset parameters may be accessed and modified directly from the Matlab commandline. eeglab now recognizes "plugins," sets of eeglab functions linked to the eeglab main menu through an "eegplugin_[name].m" function (Ex. >> help eeplugin_besa.m).
Usage:	1) To (re)start eeglab, type >> eeglab % Ignores any loaded datasets 2) To redaw and update the eeglab interface, type >> eeglab redraw % Scans for non-empty datasets >> eeglab rebuild % Closes and rebuilds the eeglab window >> eeglab versions % State eeglab version number >> type "license.txt" % the GNU public license >> web http://sccn.ucsd.edu/eeglab/tutorial/ % the eeglab tutorial >> help eeg_checkset % the EEG dataset structure
