[Eeglablist] How to comput the average of ERSP among participants?

[Lili Wu]

Hi,
  Has anyone do the suming and averaging of ERSP among different participants?
   
  Supposing that there are 5 subjects(5 *.set files), could I compute the ERSP of every subject and just add the 5 *.mat files to get the sum, and then devided the sum by 5 to get the average ERSP?
