Yes I did run mri_info, these are the results:

did you run out of disk space? Can you run mri_info on it?

Hi Freesurfers,I'm trying to remove some dura which affect my surfaces with

the command 

recon-all -skullstrip -clean-bm -gcut -subjid

but then I can't use tkmedit to check that.
The message I get is:

Error: Loading volume brainmask.gcut.mgz Couldn't read the anatomical
volume. Tkmedit couldn't read the volume you specified. This could be
because the image format wasn't recognized, or it couldn't find the proper
header, or the file(s) were unreadable, or it was the wrong size.
 
Actually I did check in brainmask.gcut.mgz directory properties, and I saw
the size of image is something like 150 KB, instead of 1 MB like is
brainmask.mgz.

What is the problem?

Thanks,
Claudia
