Hi,

I convert a thickness file to ascii format and the file looks like

(vertex id, x, y, z, thickness)

000 -36.19709 -19.27060 66.10529 2.61633

001 -16.37191 -69.16402 59.60456 2.18290

002 -10.58665 -10.65137 50.24026 2.06269

003 -22.09574 43.85081 28.52032 1.54455

004 -57.95597 -0.45362 12.97830 2.41985

005 -48.57283 -51.02512 46.88505 2.08371

I want to do some customrized smoothing and need to know the neighborhood of a vertex. I think FreeSurfer also uses this neighborhood information in random field modelling. Could you provide some information about how to get the neighborhood?

Thank you,

Ron
