Hi Tamir
I guess a quick and dirty way to do it would be to use mris_expand to create a
surface 1mm out from the white, then fill that with mris_ribbon (or maybe
mris_fill?). That would probably leave small holes. An alternative would be to
use some kind of non-maximum suppression, but I'm not sure we have anything out
of the box. I guess it depends on what the properties of the boundary are that
are important to you.
cheers

Subject: [Freesurfer] Single voxel grey-white matter boundary binary mask
External Email - Use Caution
Dear FreeSurfer experts,
Is it possible using the FS tools to create a grey-white matter boundary binary
mask in volume space (e.g., a nifti file) that will be a single voxel thick
along the entire grey-white matter boundary?
Many thanks,
Tamir
