Free surfers --
I am collecting data from dogs. Any advice regarding passing this data through the system? I have a couple of specific questions:
1) 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?
2) 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
