Hi Abby – When you say you have successfully processed a subject on that machine before, what FS version was that with? What has changed since then? The last I remember memory allocation issues, they were years ago in a very old version of OSX that we don’t even distribute binaries for any more, so I don’t think this is the same problem.

I am running into the same memory allocation issues on my Mac that were present in earlier versions of Freesurfer/Tracula. See below: MRIallocSequence (218, 182, 1):could not allocate 158784 bytes for the 44th slice Cannot allocate memory I have attempted the pre-processing with multiple and single subjects. I have successfully processed a single subject on this machine before, and have not updated to the latest Freesurfer since that subject (as all MPRAGE scans were reconstructed is FS 5.3). There is sufficient memory available and the MPRAGE scans were reconstructed correctly. Any thoughts on how to solve the issue would be appreciated. Please let me know if you need any additional information. Thanks! Abby
