Hi Avram,

not sure if it will work, but it certainly shouldn't crash. If you put the data somewhere I can get it (e.g. on our filedrop) I'll take a look.

All,

I am interested in using mri_watershed to remove the skull from an inplane low res structural scan (not an MPRAGE). However, when I try to I get the following message followed by the program crashing.

I am sure that I am missing some simple flag. Does anyone know a solution to this before I run off and start using BET.
