[Eeglablist] How can I export the mean amplitude within eeglab

[Stephen Politzer-Ahles]

Hi Yunzhe,

I don't have an answer to your first question because I'm not familiar with
ERPLAB.

As for getting mean amplitudes, I'm not aware of any point-and-click way to
do it within EEGLAB. I just do it using some simple MATLAB script. (For
example, if a given subject's data for one condition is loaded, that ERP is
in *mean(EEG.data,3)*, so you can get the mean from X to Y by doing
something like *average=mean(EEG.data,3);
meanamplitudeXY=mean(average(X:Y),2);* ). I usually write a MATLAB script
to do that for all subjects in all conditions and export it into Excel,
where I can organize it however I want and then paste into SPSS.

Best,
Steve Politzer-Ahles
