[Eeglablist] Separate the data into suitable short data epochs ?

[Sarnthein Johannes]

Hi Arnaud,

somehow I got disconnected from the ICA list and could not find the threads on the web.
so here I might ask a question that has been answered many times.

For getting artifacts out of continuous data you recommend
2. Separate the data into suitable short data epochs. 

I have a data set of 5 minutes. What do you mean by suitable?
Does EEGLAB provide a chopping function or do I do the chopping in matlab?

Best,
Johannes
