[Freesurfer] Sulcal depth units

Dear Freesurfer experts, I am reading the manuscript "Cortical Surface-Based Analysis II: Inflation, Flattening, and a Surface-Based Coordinate System" by Fischl, Sereno, and Dale (1999) where the estimation of sulcal depth is described on page 199, however from the description I am still

Re: [Freesurfer] Surface based smoothing

Hello all, I am trying to determine the neighbors and weights used in the smoothing implemented in the surface based smooth used by freesurfer (e.g. as called by mris_preproc). Can anyone point me to the code that performs the surface based smoothing in freesurfer? Thanks in advance, Simon
