I'm not familiar with BioPac either but we sometimes have *.edf files and I agree with Steve - we use 64-bit Windows 7 with 20 GB RAM on the computers running Matlab and we've never had a problem even with huge datasets. <br>

General recommendations include epoching or downsampling your data in the native software before importing (however, this may not be desirable for you if you're planning on running ICA on continuous data or analyzing high frequencies); I've also heard that switching to a Unix-based OS solves a lot of the memory problems, and in my own experience using 64-bit Windows 7 with at least 8 GB RAM took care of memory problems I was having in XP. Maybe others on the list will know some more specific solutions for BioPac data.<br>

<br>
I am trying to run analysis though EEGlab after collecting EEG data from<br>
our BioPac unit. I have tried exporting files in .txt, .mat and .edf<br>
format with no luck (memory seems to be insufficient). Is there a way<br>
that EEGlab can read files from a BioPac? I have seen that a few people<br>
have asked the same question on the archives of previous questions but<br>
there was no answer given.<br>
<br>
Any help would be greatly appreciated.<br>
<br>
Many thanks,<br>
