Are you running the latest release version? Would it be possible to send us the surface file and the overlay file that crashes?
Best, Ruopeng

Hi all, I am trying to overlay a map on a specific subcortical structure (the caudate).
-I obtained the surface of the structure using the command:
mri_tessellate structure.nii.gz 1 lh.structure.surf
-then I projected my map on the surface using:
mri_vol2surf --mov map.nii --regheader structure --hemi lh --surf structure.surf --projdist 0 --fwhm 5 --out projected_map.mgz --interp trilinear
Everything seems to work properly. I am able to see the result using tksurfer.
However, when I try to overlay projected_map.mgz on lh.structure.surf using freeview I experience a segmentation fault issue. It seems that the software looks for the WM, the pial, the curv, etc surfaces. Obviously I don't have these information, since I am projecting the map only on the caudate nucleus.
Could you give me an advice about that?
Thanks Maria
