[Freesurfer] How many regions does "aparc.DKTatlas+aseg.mgz" have?

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. https://secure-web.cisco.com/1fBJMEihMTm8S1YZKy0FxnEoJxLOAxKaZC0-l90ulKxJmiT...

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.
