it sounds like you ran out of memory. How much RAM do you have on your
machine?

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
