Dear Geoff,
You could mri_convert raw volumes that label voxel sizes twice than they really are. To my experience, this overcomes quite some problems.
Hope this helps, Denis

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
