[Eeglablist] Information about different in ERP/ERSP

[Daniele Lozzi]

Hello Ivano, thanks a lot for your answer!
My goal is to compare two channels in the same condition. I have extracted
the ERPs from the events and would like to plot the two channels and the
p-value of the t-test, just as I do for two different conditions on the
same channels, but I can't figure out which commands to write to do this
plot or to get the numerical data to plot later.
Thank you very much for your support!

Regards

Daniele
