Hi Chung,

There is no menu item for dividing the data into regular intervals yet, but the eeg_regepochs should do what you want from the command line.

The following should come pretty close to producing what you described:

EEG=eeg_regepochs(EEG,'recurrence',2,'limits',[-2 0]);
EEG=eeg_checkset(EEG);

Subject: [Eeglablist] How to segment this continuous data into a regular time windows?

Dear all,

I have obtained single continuous EEG data,
and I want to know how to segment this continuous data into a regular time windows from the recording starting point (e.g. 0 ~ 2 sec, 2~ 4, 4 ~ 6, ...) regardless of event markers.
Is there any applicable menu in EEGLAB or function that I can use in the command line?
If there is, please let me know how to go about writing an appropriate script.

Thanks a lot in advance!
