Hi Bruce and Satra, Our specific goal is to measure the vermis. It's time consuming to do it manually, so my idea was to ask if it could be possible to develop an automatic segmentation/parcellation procedure, similar to aseg, that includes also the vermis. (In addition, we have three subdivisions of vermis.) I do realize that reconstructing the cerebellar surface is a very difficult task because of the spatial resolution issue but maybe a volumetric approach similar to aseg could be feasible?
Hi Satra,
we do segment the cerebellum with the aseg stuff into cerebellar gray and white. I guess it's a question of what your goals are Lars.

Hi Lars,
yes, probably the aseg would be a better way to do it. Is the vermis only distinguished on MR by it's location or are their signal differences between it and surrounding tissue (forgive my ignorance)?
