Ideally, you should have edited the aseg.presurf.mgz, then rerun
recon-all starting just after the aseg. That said, if you edited the
aseg.mgz and then re-ran that mri_segstats command, the stats should
have changed.

Dear FreeSurfer experts,

However, I still got no increased numbers in the volumes that I edited
on aseg.presurf.mgz via Freeview. However, I observed an increase
under "Surface Hole" item. Should I care about it?
I'm using FreeSurfer 7.3.2 on Linux (OS Name: Ubuntu 23.04).
Thanks a lot!
Yours faithfully,
Krystal

*Subject:* [Freesurfer] [FreeSurfer] regeneration of aseg.stats from
manually edited aseg.mgz
External Email - Use Caution
Dear FreeSurfer experts,
I edited some images that under-segmented the brain by coloring the
missing brain regions. When I used the edited aseg.mgz to regenerate
aseg.stats, the new statistics did not show the increase of the
volumes that I edited. Please see the following command lines that I
have run on Linux:
mri_segstats --seed 1234 --seg mri/aseg.mgz --sum stats/aseg.stats
--pv mri/norm.mgz --empty --brainmask mri/brainmask.mgz
--brain-vol-from-seg --excludeid 0 --excl-ctxgmwm --supratent
--subcortgray --in mri/norm.mgz --in-intensity-name norm
--in-intensity-units MR --etiv --surf-wm-vol --surf-ctx-vol
--totalgray --euler --ctab $FREESURFER_HOME/ASegStatsLUT.txt --subject
Sub-180
May I know what step(s) I have missed before generating the
aseg.stats? Please kindly advise. Thank you very much!

Krystal
