Hi, Yujing

Thank you for reply. It is likely that the version of freesurfer is different. The latest version (7.4.1) output results based on three atlases. https://secure-web.cisco.com/16kyFKZBTTmJxzWlCpHckTWKfW7NeWPN9nduq80zrB4veUg...

Thanks, Kei

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

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" claiming to be https://secure-web.cisco.com/132WvSeoaXEyy8CpFxjt9yVSLNRqcdk9XlE2pYSq33zz-bh...https://secure-web.cisco.com/1fBJMEihMTm8S1YZKy0FxnEoJxLOAxKaZC0-l90ulKxJmiTJlTMxY3q3ryv_7ts1uTTCPQdTCOXuEDbwL3_YFKQ9x83aJYfbcz7J81AdtRga---yQ-peSn5Fsu8zcLmGfTkyEBLwe7jTpR76XJKk8WD2KrGzdLzn-OGCPsb6KrE26Sry5Xtdonatr3zpx1586ZVun-Dfymo1VrwMbfxb50BE9Jrg_eO4NI1aY2u0E2Gb7sy0Z297RPfygrH9Q30T_pzzmgkx2eR0deWv8TDMkcMYeNHWrmhhENpTODcS5c85PLV66Hz7SIC-1D62zGk2eaK5kt2QcMtZN59t4JRmmXw/https%3A%2F%2Fsurfer.nmr.mgh.harvard.edu%2Ffswiki%2FFsTutorial%2FAnatomicalROI%2FFreeSurferColorLUT

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
