Re: [Freesurfer] mri_vol2surf sample inside and outside of pial

yes, although note that neither one is guaranteed to be "inside" or "outside" at that distance (it might reenter the surface in the outwards normal direction, or leave the surface in the inwards direction)

Hi,

I have a short question concerning the mri_vol2surf command. Do the following parameters of the command return the maximum volume value (for each vertex) which occurs between 10 mm outside and 10 mm inside the pial surface (along normal vector)?

--projdist-max -10 10 0.25 --interp nearest --surf pial

Thank you very much!!
