Try running it with --no-aseg. doug

Hello,

I have run into an error while trying to make an average subject using 200 scans.

When I ran this command I got an error: *make_average_subject --xform talairach.xfm --out 200avgsub --subjects*

The error:

Allocing output
mri_concat(40491) malloc: *** mmap(size=262144) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
MRIalloc(256, 256, 256): could not allocate 262144 bytes for
13726th slice

Cannot allocate memory
WARNING: could not create average segmentation for aseg ...
  ... but continuing

make_average_volume done

The average sub folder does not contain aseg.mgz and p.aseg.mgz files.

*The version of Freesurfer I am using:* v 1.313.2.6 2010/08/04 15:50:56 nicks *My memory:* 8 GB 1333 MHz DDR3 *Hard-drive:* 276.49 GB free MAC OS X v 10.6.8

I have scoured the archives for the answer to my question to no avail. All of the answers before seemed to revolve around versions of Freesurfer which I expect were updated. Nick Schmanksy wrote "sorry, i meant to say include the --no-aseg flag with make_average_volume (make_average_subject is just a wrapper script that calls make_average_volume and make_average_surface)." But wouldn't this prevent segmentation? Is there a way to then add segmentation after? Sorry if these are novice questions (as I am a novice).

Thank you,

Adam
