Sorry, fell thru the cracks the first time. Which version of freesurfer
are you using? The stable versions do not allow writing of mgh files
from mris_convert. I've put a new version here:
ftp://surfer.nmr.mgh.harvard.edu/transfer/outgoing/flat/greve/mris_convert
See if that works

Hi Freesurfer Community,
I sent this message to the mailinglist a little bit ago. It never
showed up in my mailbox, although it seems to have posted on the
mailinglist website. Anyway, on the chance that it didn't mail out
properly, I thought I'd resend it, as I still havent been able to
figure out what I'm doing wrong.
Thanks!
Emily

Hi,
I have a question about using mris_convert to convert .asc to .mgh. I
have a .mgh file I made with mri_vol2surf (target subject as
fsaverage). I convert it to .asc using this command:
mris_convert -c 010.onerun.space.intval.lh.fsave.mgh tkregister2/
/home/ecooper/subjects/fsaverage/surf/lh.white lh.010mg2txt.asc
then I try to convert it from .asc to .mgh using this command:
mris_convert -c lh.010mg2txt.asc
/home/ecooper/subjects/fsaverage/surf/lh.white lh.010mg2txt2mg.mgh
but when I try to load the new .mgh (lh.010mg2txt2mg.mgh) in tksurfer
as an overlay:
tksurfer fsaverage lh inflated &
I get this error:
% Loading tal xfm file
/home/ecooper/subjects/fsaverage/surf/../mri/transforms/talairach.xfm
MRIalloc: could not allocate 443 slices
Cannot allocate memory
From the documentation of mris_convert, it seems that
lh.010mg2txt2mg.mgh should be identical to the original .mgh
(010.onerun.space.intval.lh.fsave.mgh). Is mris_convert unable to
convert .asc to .mgh? Or is there something wrong with my commands?
Thanks for your time!
Emily
