Hi Fereshte mris_volumes computes and prints the volume of the interior of a closed surface (a single number). It does not fill the interior. For that, use mris_fill cheers Bruce On Tue, 19 Sep 2017, Fereshte wrote: Dear Professor Bruce  I'm just trying to convert lh.pial surface to the vol

Dear Professor Bruce I'm just trying to convert lh.pial surface to the volume with the down below command but the output doesn't make any sense ( lh.voulme contains zero). Could you please help? Mris_volume topo_defect_after/surf/rh.pial Thank you! On Tue, Sep 19, 2017 at 1:11 PM Fereshte wrote:
