Hi Freesurfer experts,

I was working on to conduct the local gyrification index analysis. I am getting the following error message when I used the option -localGI in recon-all.

--------------------------------------------------------------------

Improper assignment with rectangular empty matrix.

Error in dsearchn (line 79)

[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!

--------------------------------------------------------------------

I have seen people have similar problem long time ago ( https://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg33701.html).

I also tried to check the SearchProjectionOnPial.m file and it looks same as what was attached in the email.

Can anyone help on this?

I will really appreciate.

Thank you,

Hari
