Hi Niels
I don't see why not. vol2surf takes the surface location and the surface
normal and sampled from the volume onto the surface using those two pieces
of local information. Global surface topology shouldn't matter

Dear list
I am working on a project in which we want to extract hippocampal surfaces
using mri_tessellate and then overlay these surfaces with fmri activations
from nifti files using mri_vol2surf. However, I am unclear whether
mri_vol2surf can be used for surfaces derived from subcortical structures
like the hippocampus. Crucially, these structures are unlike the cortex in
that they have a closed shape and therefore the projection of activation to
a surface may be more complex than in the case of cortex (which surface
normal should one take?). So I guess my question is whether mri_vol2surf
works for these kinds of surfaces or whether some other approach should be
used. Thanks!
Niels
