Dear Douglas, Thank you for your kind reply and instruction. But I still have a few questions: 1. how can I get the segmentation for BA areas, which have no hemisphere bases? 2. when the cortical atlas is changed, should the '--wm-annot’ be changed accordingly? For instance, use '—wm-annot

There are several layers of difficulty here: 1. If you just wanted to use a different cortical segmentation, say, aparc.a2009s or aparc.DKTatlas, then you can run gtmseg with --ctx-annot aparc.a2009s 11100 12100 or --ctx-annot aparc.DKTatlas 1000 2000. The numbers are the base numbers in

Dear freesurfer support, I am using the PetSurfer to process our PET data. But by default, it would only generate stats for the segmentation with the aparc atlas. However, I want to obtain the stats for different freesurfer atlases, like in the freesurfer outputs (aseg,stats,
