External Email - Use Caution Dear Freesurfer experts:
I am on ROI analysis tutorial: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/AnatomicalROIV6.0 And I am trying to understand the relationship between: /label/?h.aparc.annot and /mri/aparc+aseg.mgz /label/?h.aparc.a2009s.annot and /mri/aparc.a2009s+aseg.mgz I understand /label/?h.aparc.annot corresponds to "Desikan-Killiany atlas" and its labels have 35 different labels (except unknown 0), while in several cases you mentioned that "/mri/aparc+aseg.mgz" corresponds to "Desikan-Killiany atlas", which I DO NOT understand. "/mri/aparc+aseg.mgz" to me are subcortical segmentations while "/label/?h.aparc.annot" are cortical(surface) parcellations. "Desikan-Killiany atlas" should mean "cortical (surface) parcellations". That's why I do not understand why "/mri/aparc+aseg.mgz" corresponds to "Desikan-Killiany atlas"? Could anyone help me understand this?
