% 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 eegplugin_besa.m).
%
% Usage: 1) To (re)start EEGLAB, type
%            >> eeglab           % Ignores any loaded datasets
%            >> eeglab nogui     % Do not pop up GUI
%        2) To redraw 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"           % the EEGLAB open source license
%   >> web http://eeglab.org    % the EEGLAB tutorial
%   >> help eeg_checkset        % the EEG dataset structure
