Hi all,

In recon-all pipeline , mri_segstats runs with -pv mri/norm.mgz option ,as written from http://surfer.nmr.mgh.harvard.edu/fswiki/mri_segstats , it is used to compensate partial voluming. I wonder what exactly does this do, as the volumes given by aseg.stats are different from aseg.mgz and why is it more accurate ? I will appreciate if anyone could help to clarify this .

Thanks
