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.

Hi all,
I have a 'lh.thickness.asc' file which contains thickness values of each vertex.
The format of the file is following;
<vertex index> <x> <y> <z> <thickness>
However, x,y,z are not integer. What is the unit of the x,y,z values in the file? I am trying to find all the neighborhood of any given vertex as x,y,z -> x+1,y,z etc, can you suggest a method for this problem.
Sincerely yours,
Onur
