that shouldn't be the case. Run mris_info or mris_euler_number on your
input surface. Can you load the thickness as a surface overlay? It may be
that you regenerated surface and not the htickness, or visa-versa. Which
surface are you using?

Hi Bruce,
Thank you so much for the answer.
I have used "read_surf.m" function and got the list of vertex locations and
a list of faces. However, the list contains 107106 vertices whereas the
lh.thickness.asc file contains 118603 vertices. How can I match the
thickness values which are inlh.thickness.asc file with the vertices which
were obtained from "read_surf.m" function?
Sincerely yours,
Onur

Konu: Re: [Freesurfer] Neighborhood of a vertex
Hi Onur
for that you need a surface file. If you are using matlab you can load a
surface file in with read_surf.m. The <vertex index> will then be an index
into the surface (although note that you will need to add 1 to it since
matlab is 1-based when you index into the vertex list). It will return a
list of vertex locations and also a list of faces. The faces contain the
(0-based) indices of the vertices in each triangle, which can be used to
compile a list of neighbors.
cheers
Bruce
