can you give us the command line you used? And what the SUBJECTS env variable was (if you used it)?

Dear freesurfers, I am coming across an error in the beginning of
make_average_volume of make_average_subject where mri_convert fails.
make_average_surface finished without a problem so hopefully that part will
not need to be re-run. I've check permissions, cpu space, paths but couldn't
find anything... Any help/suggestions would greatly appreciated. Below is
the error message:
