[Freesurfer] mri_mask bug

Hi,

We were running free-surfer (freesurfer-Linux-rh9-dev20051003-full.tar.gz) on RedHat 9 and encountered a problem with the command mri_mask. It is not at all working.

Here is what we entered as input: mri_mask input.mgz mask.mgz output.mgz

No matter what we put as the mask, the input.mgz and output.mgz are always identical. Is there a bug with this command? (The command says "writing masked volume to output.mgz..." then about 10 seconds later it's done - although nothing is done).

Thanks.
