      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
