Yes, the easiest thing is going to be to treat them like a functional volume. For this, you'll need a register.dat file. This can be created with tkregister2 (run with --help for docs). Basically, you'll need to register the volume that you drew the ROIs on to the freesurfer anatomical. Use the source volume as the --mov and the freesurfer as the --targ. Then you can use mri_vol2surf to sample onto the surface.

Hi,
I'm trying to do something I think is pretty easy. I created some ROIs in
afni(that I also have
in analyze format). I would like to overlay them onto inflated and folded surfaces produced in freesurfer. Should I treat these as functional overlays and treat it as functional data or is there another way? Thanks,
