Hello FreeSurfer Team,
I am trying to compute the local Gyrification index on my subjects with
recon-all -s <subj> -localGI. Running this under FS 6.0 runs without errors,
with FS 5.3. I get:
mesh_outer =
struct with fields:
vertices: [68598x3 double]
faces: [137192x3 double]
facesOfVertex: [68598x1 struct]
preparing pial mesh structure ...
...searching for mesh edges...done (82.56 sec).
... creating path file for vertex 1 / 68598
area file for outer ROIs saved at 1
{Unable to perform assignment because the left and right sides have a different
number of elements.
Error in dsearchn (line 84)
[d(i),t(i)] = min(sum((x-yi).^2,2));
Error in mesh_vertex_nearest (line 29)
nearestIndex = dsearchn(vertices,points);
Error in reorganize_verticeslist (line 28)
[nextindex,nextvalue]=mesh_vertex_nearest(mesh_total.vertices(remaininglist,:),mesh_total.vertices(verticeslist(start_vertex),:));
Error in make_roi_paths (line 93)
reorglist = reorganize_verticeslist (mesh_total, A, mesh_outer, perim,
verticeslist, step);
}
>>
ERROR: make_roi_paths did not complete successfully!
Now I wonder why the computation works in version 6 but not in 5.3. My subjects
are originally reconstructed with version 5.3., does the computation for local
Gyrification Index differ between both versions or can I just run the command
in FS6?
Cheers
Philipp
