Hi Kei,
Here is my calculation:
198 aparc.a2005s+aseg.mgz
192 aparc.a2009s+aseg.mgz
114 aparc+aseg.mgz
I can't find aparc.DKTatlas+aseg.mgz in Freesurfer distribution directory. Is
it the same as aparc+aseg.mgz?
Best,
Yujing

Subject: [Freesurfer] How many regions does "aparc.DKTatlas+aseg.mgz" have?
External Email - Use Caution
Hello FreeSurfer Developers,
We ran recon-all on a 3D T1-weighted image, by default.
ls *.nii | parallel --jobs 2 recon-all -s {.} -i {} -all -qcache
Our question is very simple.
How many regions does "aparc+aseg.mgz" and "aparc.DKTatlas+aseg.mgz" and
"aparc.a2009s+aseg.mgz" have in each?
We checked the links below. And we want to renumber the region index from 0 as
shown in the photo below.
MailScanner has detected a possible fraud attempt from "secure-web.cisco.com"

However, the number of regions varies slightly depending on the subjects
(103~106 in aparc.DKTatlas+aseg.mgz).
Therefore, we want to know the number of regions in three parcellation map.
1) FreeSurfer version: freesurfer-linux-ubuntu20_amd64-7.4.1.tar.gz
2) Linux ~~~ 5.15.0-76-generic #83~20.04.1-Ubuntu SMP Wed Jun 21 20:23:31 UTC
2023 x86_64 x86_64 x86_64 GNU/Linux
