Hi,<div><br></div><div>I am a relatively new EEGLAB user, running EEGLAB and ERPLAB with Matlab 7.13 (2011b) on my Dell PC (2.66GHz, 196GB RAM) with Windows XP 2002 (SP3). I have subject files that are broken into two pieces which are about 60MB each. I am struggling to complete analysis with this data as a result of its size -- my greatest problem thus far being my near inability to view the data using eegplot(). So far, I have been able to see my data only once in EEGLAB, when I have both changed Microsoft's options to allocate 3GB instead of the default 2GB, and when I have loaded only 10 seconds of data. With 10 seconds of data, it takes several minutes for the eegplot() gui to load (meanwhile the computer is nearly paralyzed), and it appears as though almost the entire set of events is put into the data (incorrectly - there should be maximum of 30 events, not 3000+).</div>
<div><br></div><div>My question is, does anyone know a useful work-around for such large datasets, whether it be dividing the data into segments manually before loading into EEGLAB (and, if so, how best to divide the events accordingly), or if there is some better way to work with EEGLAB using the large files as they are (which would certainly be ideal).</div>
