Hi Pierre,
I guess the 'mni_getmesh.m' writted by Moo K. Chung is used to do what you want. Here is the link:

Hope it can help you.

主题: [MINC-users] from surface to adjacency
Dear minc users,
I am currently trying to adapt a region-growing procedure for surface data.
The procedure is using a representation of the adjacency matrix between
vertices, i.e. a matrix (vertices times vertices) with 1s for pairs of
vertices that are spatial neighbours on the surface, and 0 otherwise. I sort
of understood that the order of the vertices in the obj file is very
specific and follows an iterative refinement of the surface grid. Can anyone
suggest an approach to generate the adjacency matrix based on the .obj data
?
Thank you in advance,
