[Freesurfer] Seg fault during wm_fill

Folks --

I'm working with a dog brain. With the help of Denis Fize, I've "tricked" freesurfer into treating my 0.47 mm voxels as 1 mm voxels, and I have manually stripped the skull. I used the automated routine to segment white matter and then manually erased the brainstem and cerebellum. Now, however, when I try and apply the automated white matter fill routine, the operation fails with "Segmentation Fault" after several minutes of processing. I've provided left and right hemisphere seed points, as well as a callosal seed point.

This is a fairly unusual data set, but I would appreciate any advice...

Thanks,

Geoff
