I've never seen a dog brain, but macaque brain requires .3mm or so voxels. Various pieces may not work (e.g. cutting planes will certainly fail), but there should be manual interventions for any pieces that fail.

Free surfers --
I am collecting data from dogs. Any advice regarding passing this data through the system? I have a couple of specific questions:
- Should I acquire data with voxel sizes smaller than 1mm, given that
the brain is much smaller? How would I tell free-surfer to operate with this higher resolution data?
- So far, automated skull stripping has been a failure, even with
definition of a "seed point" in the white matter. The routine strips away the brain around the seed point, leaving a large chunk of scalp and muscle with a bit of cortex attached. Any thoughts on how to get this going?
Thanks in advance for any help,
Geoff
