Dear Freesurfer specialists,
I'm currently working on a comparison between manual segmentations and freesurfer segmentations of the hippocampus. Therefore i would be very interested in the atlas used for subcortical segmentation. On the wiki i read that the manually labeled brains used to build this atlas are about but not completely the same as the ones in the Desikan atlas, namely 39 manually labeled brains by Rahul Desikan. Could you please provide me with some rough sample descriptives on the brains used in the subcortical segmentation atlas, i.e. Age of subjects, male/female? That would be wonderful!
Has this atlas changed in any way between version 4.5 and 5.1?
As I am specifically working with the hippocampus segmentations, it would also be very interesting to know what the mean size of the hippocampus in this sample was – do you by any chance have some information on this?
Thank you very much for your help!
Cheers, Elisabeth
