<br>
after you use the EEGLAB graphic interface to divide your dataset, look at the EEGLAB history using the "eegh" command. The last line will contain the command you will need to perform the same operation in a script.<br>

Up until now I've been doing it by simply using: Eidt -> select data -> epoch range, but it takes ages to do it manually. Is there any way to do it using script, so that Matlab checks number of events in every dataset at first, and then takes the 1st and 2nd half separately?<br>
