Did you run out of disk space? The recon could have been aborted during the middle of the write (but unlikely). If the edits were in the brainmask, then there is not much you can do. If the edits were not in the brainmask, you can just rerun starting at the brainmask and the edits will be preserved.

Hi all,

After doing some manual edits to the wm and pial masks, I recently had a recon fail with the following error:

mghRead(/subject_177/mri/brainmask.mgz, -1): read error

Invalid argument

mri_em_register: could not open mask volume brainmask.mgz.

When trying to load either the brainmask.mgz or wm.mgz into freeview, these also fail, e.g.:

mghRead(/subject_177/mri/brainmask.mgz, -1): read error

MRIread failed: Unable to read from /subject_177/mri/brainmask.mgz

All other volumes load fine.

Can you think of what I might have done to corrupt these volumes? And is there a way to revert to the most recent version, so that I don't lose previous edits?

Thanks so much, Rachel
