I see now that recon-all produces

aparc.DKTatlas+aseg.mgz

aparc.a2009s+aseg.mgz

aparc+aseg.mgz

 

Just to clarify, my calculation is based on fsaverage/mri/aparc*.mgz

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.

MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://surfer.nmr.mgh.harvard.edu/fswiki/CorticalParcellation

 

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://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROI/FreeSurferColorLUT

 

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

 

 

Thanks,

Kei
