Check your log. If gcut detects that the gcutted brain is much smaller than the original brain, it will assume that something bad has happened and it won't write brainmask.gcuts.mgz. This may be what is happening in your case. To fix this, you can adjust the watershed threshold or add something like 'mri_gcut -T 0.3' to your expert options file. The lower the threshold passed to mri_gcut -T, the less likely gcut will be to remove too much brain.
