External Email - Use Caution

Hi Freesurfer users

I search the FS documents but can’t find a way to extract the vertex neighborhood for a particular vertex. I’d like to use data associated with the vertices in the neighborhood. In 3D space, we often use such kernels for filtering.

Thanks!

Best regards,
