Dear FreeSurfer community, I am a statistician who knows shamefully little about brain anatomy and I am writing with a request.
I don’t have easy access to Freesurfer and the original data but have the final text output i.e., the /stats folder, from a large cohort, which including *h.aparc.a2009s.stats. I have been attempting to assign higher-order labels to the 74 Destrieux parcellations. 1) Categorizing uniquely into the 4 lobes: frontal, occipital, parietal, temporal; 2) Categorizing uniquely into “types of networks”: limbic, paralimbic, unimodal, heteromodal, subcortical, primary; 3) sensory-motor modality: somatosensory, visual, auditory, motor As far as I understand these higher-order assignments of the 74 parcellations are not uncommon although not all cases are clear-cut so some knowledge of anatomy is needed (assuming that I am indeed looking at the correct level – gyri and sulci in the aparc.a2009s.stats file). If so, would anyone mind sharing a text file with the correspondence between the 74 parcellations and lobes, network types, and/or modality? I’d be very grateful for any guidance and help. Thank you kindly, J Evans
