[Eeglablist] Re: t tests in comp_erps

[A P Basu]

I have a question to clarify something about the t-tests in
pop_comperps. 

I have data from 9 subjects for a before and after condition for 32 EEG
electrodes, for a 4s epoch with a sampling rate of 250. 

Question one: to clarify that the ttests are being done to compare the
averaged ERPS before and after for the 9 subjects 

Question two: does the program perform any correction for multiple
comparisons?

Many thanks for your help. I am really enjoying using EEGlab to analyse
the data.
