You can smooth it. This would give you a gaussian kernel instead of the box kernel that you describe. Set the fwhm to the radius you want (mris_fwhm with --smoothonly option)

Hi Freesurfers,
Thank you for the help you provide through this list.
Is there a way to get, for each vertex, the identify (or thickness values) of the surrounding vertices in a 10mm radius? The command mris_convert has the '-v' option, but that produces only 5-6 vertices and there is no option to query a particular radius.
I imagine this can be done manually outside Freesurfer by first identifying the neighbors for each vertex based on the coordinates, then getting the respective thickness value, but I wanted to check whether there is any easier way or any advice on how to proceed.
