[Eeglablist] Epoching resting state EEG

Dear Eeglablist,

I have been trying to epoch resting state EEG data. So far, I have the
following script:

"ELength=1;
Frames=EEG.pnts;
Sampling=EEG.srate;

for Epoch=1:Frames/(ELength*Sampling)
    EEG.event(Epoch).latency=ELength*Sampling*Epoch;
    EEG.event(Epoch).type='';
end

EEG = pop_epoch( EEG, {  }, [0  ELength], 'epochinfo', 'yes');"

This gives me one-second epochs with 200 samples in each (equal to the
sampling frequency). The epoch start time is 0 and the epoch end time is
0.995.

Is this correct?

Best regards,

Eric
