Hi Siti
it is more or less the same protocol, but I exepect there are some differences as for example neuromorphometrics used differentt (probably better) visualization and editing tools. We rebuild the atlas for every release to account for changes in registration, normalization, etc....
We have multiple cortical atlases, one described by Christophe Destrieux and one by Rahul Desikan.

Hello,
I’m working on a comparison of atlas and segmentation methods. One of the atlas sets I’m using is the subset of Neuromorphometrics data from the MICCAI 2012 Grand Challenge and Workshop on Multi-Atlas Labeling. From what I understand, the “general segmentation” of the brains for this atlas was defined by the MGH Center for Morphometric Analysis, while the cortical segmentation is similar to the DKT atlas available in FreeSurfer.
I have 2 questions about the atlases used in FreeSurfer:
- Is this MGH sub-cortical segmentation protocol similar to that used in
the default FreeSurfer sub-cortical segmentation?
- Would it be possible to have more information about the atlas subjects
used in both the FreeSurfer cortical (DK & DKT atlases) and sub-cortical segmentation and are these manual labels available for download? The only description I could find on the sub-cortical atlas was from Fischl et al. 2002, but I don’t think this is the atlas set used in the most current FreeSurfer version.
Thank you and best wishes,
Siti
