Hi,

After freesurfer reconstruction, I tried to project surface normal vectors on 
the ribbon.  I used the following scripts, but the projected vectors were out 
of the ribbon when I visualized it freeview.  The vectors were placed outside 
of the ribbon.   Anyone knows any idea ? 

fslregister --mov mri/orig.mgz --s xDS --reg rrr.dat --dof 12 --tmp ./tmp/
mri_surf2surf --s xDS --hemi lh --sval-nxyz pial --tval ./pl_100.mgz
mri_surf2vol --surfval pl_100.mgz --hemi lh --surf pial --volreg rrr.dat 
--outvol pln_pribbon.mgz --fillribbon --template mri/orig.mgz


Thank in advance,
