[Freesurfer] Error: [Cannot allocate memory] having 16GB of Memory.

Dear all,

I'm having a problem running trac-all -prep. I receive this error (FROM THE TRAC-ALL.LOG WHICH IS ATTACHED):

MRIalloc(218, 182, 182): could not allocate 158704 bytes for 25th slice

Cannot allocate memory

Linux ubuntu 2.6.38-13-generic-pae #52-Ubuntu SMP Tue Nov 8 17:50:45 UTC 2011 i686 i686 i386 GNU/Linux

trac-preproc exited with ERRORS at Fri Dec 2 05:02:57 PST 2011

I am using Ubuntu 11.04 (Natty) 32bits and the kernel is 2.6.38-13-generic-pae, that is, it can use more than 4 GB of RAM (In fact, I was running it with 16GB of RAM) so we think memory was not the real cause of the problem.

The freesurfer version was: freesurfer-Linux-centos4-stable-pub-v5.1.0

Thanks and best regards.

Fidel.
