[Eeglablist] ERSP/ITC data across electrodes and subjects.

[arno delorme]

Dear Lee,

both the graphic interface of EEGLAB and the command line function  
std_erspplot.m may be used to plot channel-average ERSP and ITC. You  
are right in mentioning that the .datersp and the .datitc file contain  
ERSP and ITC data for each subject.
Best,

Arno
