POP_ENVTOPO Plot envelope of an averaged EEG epoch, plus scalp maps of specified or largest contributing components referenced to their time point of maximum variance in the epoch or specified sub-epoch. Calls envtopo(). When nargin < 3, a query window pops-up to allow additional arguments.


Usage: >> pop_envtopo( EEG ); % pop-up window mode
>> pop_envtopo( EEG, timerange, 'key', 'val', ...);

Inputs:
EEG   
input dataset. Can also be an array of two epoched datasets. In this case, the epoch mean (ERP) of the second is subtracted from the epoch mean (ERP) of the first. Note: The ICA weights must be the same for the two datasets.
timerange   
[min max] time range (in ms) in epoch to plot, or if [], from EEG

Optional inputs:
'key','val'   
optional spectopo() and topoplot() arguments (see >> help topoplot())

Outputs: Same as envtopo(). When nargin < 3, a query window pops-up
to ask for additional arguments and no outputs are returned.
