I’m wondering if freesurfer provides functions to filter the surface data within certain neighborhood exclusively on the surface. It’s essentially similar to regular smoothing in 3D space. But the filtering kernel only runs on the surface.

I can think of a solution to filter adjacent vertex in the surface file. But I’m not sure if the adjacent vertex is also close in space.

Thanks!
