Hi all, I'm running tracula and when doing the step: trac-all -prior -c single_subject

After some time it gives this error:

MRIalloc(218, 182, 182): could not allocate 158704 bytes for 49th slice

Cannot allocate memory

I' m running tracula on Ubuntu 10.04, with 4GB ram. The diffusion data is DTI with 64 directions.

This happens many times? I need more memory?
