[Freesurfer] QDEC - cannot allocate memory

Hi freesurfers,

I am on a macbook pro OSX 10.9.5, trying to run an analysis on qdec - freesurfer version 5.3. I am looking to analyze T2weighted scans for 27 subjects through the qdec system. I keep getting this error that it cannot allocate memory for the task. I'v been talking with our IT people and they've told me I have more than enough space on the computer, so it must be an issue with the program or how it's set up.

This is the error message:

*** error: can't allocate region

*** set a breakpoint in malloc_error_break to debug

znzTAGskip: tag=586130367, failed to calloc 2856323072 bytes!

Cannot allocate memory

Does anyone know what I can do to fix this problem?

Thanks,

Marissa
