Those are the number of defects in the ?h.orig.nofix. Not sure why the two people see different numbers. Are you totally sure they are being run in exactly the same way? If they made different edits (control points, brain mask) then it could result in different number of holes

Hi Freesurfer Support,

I'm wondering how ?h.surfaceholes prior to fixing and "Total number of defect holes in surfaces prior to fixing" are calculated in the aseg.stats file for each brain. I compared aseg.stats files for the same brain edited by two different people, and I noticed that there were different numbers of holes listed for each person, despite the brain being the same.

For example:
lhSurfaceHoles 130 vs 61

rhSurfaceHoles 102 vs 80

Total number of defect holes 232 vs 141

Why would those numbers be so different?

Thanks,
