Hi freesurfer developers I'm working with freesurfer's subcortical anatomical labels. I understand that they are based on a database of manually labeled anatomical scans, which were normalized to the MNI template in order to get probability maps, that freesurfer uses as prior information. In a slide (in freesurfer.recon.2007.ppt I believe) there is a line that says the atlas is RB_all_2006-2-15. What is this particular atlas based on? how many brains were manually labeled? I couldn't find any reference for this atlas.
There exist some probabilistic cytoarchitectonic maps (cf Eickhoff NeuroImage 2005). I understand that freesurfer only makes use of manually labeled MRI scans, not cytoarchitectonic information. Is that right? how hard would it be to use the probabilistic cytoarchitectonic atlas instead of RB_all_2006-2-15? is it doable at the user level or does it require messing around with the code? Thank you very much in advance! - Julien _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
