Dear Freesurfer team,
I have a question about the inconsistency between the vertex read from
read_surf and vertex shown in Freeview.
I have a volume from the hippocampal subfield pipeline and I converted it to
surface mesh using
mri_tessellate mri/lh.hippoAmygLabels-T1.long.v21.mgz -an
surf/lh.hippoAmygLabels-T1.long.v21.surf.
Then I smoothed the surface using mris_smooth
surf/lh.hippoAmygLabels-T1.long.v21.surf
surf/lh.hippoAmygLabels-T1.long.v21.surf
Now I want to get the corresponding voxel of lh.hippoAmygLabels-T1.long.v21.mgz
with the vertex. In Freeview, for example, the vertex 0 is [5.17, -19.5, 4.83].
I know how to convert this vertex to the corresponding voxel.
However, when I read the surf/lh.hippoAmygLabels-T1.long.v21.surf from Matlab
using read_surf, the first vertex ( vertex(1,:,:)) is equal to
[165.4900,217.3600,-159.7300].
Are there any ways to solve the issue?
Thank you.
Regards,
Shizuka
