HI, I've got some 3T SPGR data (512 x 512 x 104, vox dim. 0.488 x 0.488 x 2). I seem to be able to convert them to .mgz ok, but when I run mri_watershed I get an error saying "main radius too high" (output below). Any ideas as to what's happening? Thanks, Alex
mri_watershed 1001670.mgz 1001670_brain.mgz
