[Eeglablist] Save EEG epochs in different files

[Alberto Cacciola]

Dear all,
many thanks for your help and quick response.
I fixed the problem creating a loop to save each epoch one at a time.
If it can help someone, here it is:

for i=1:size(EEG.data,3)
        x = double(EEG.data(:,:,i));
        dlmwrite(['epochs\Epoch_' num2str(i) '.txt'],x,'\t')
end

Makoto, I would need to import different data epochs in LORETA software for
subsequent analysis(maybe it is not even necesarry but I am trying
different apporaches).
Sorry for the strange question!!:)


Best
Alberto
