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?
