Hi list,I wonder whether is possible to:1) obtain cortical thickness from cerebellum and its subregions2) use cerebellum (or its subregions) as seed for FS-FAST analysis? Thanks in advance Kind regards

No, not with FreeSurfer. Cerebellum has such a fine cortex that you need resolution on the order of microns to actually get it properly.

Yes. When you run fcseed-config, specify the cerebellum (8 and 45). If you have a subsegmentation of cerebellum, you'd have to specify the proper number
Thanks in advance
Kind regards

I think Iman (ccd) has some tools that would let you calculate cerebellar thickness from our aseg. Not sure how accurate it will be biven how small some of the foliations are
