Hi Mark,
Thank you for your reply. The reason I am interested in using the thresh boundary correction option is because none of the cerebellum segmentations I have run using the fast boundary correction option are completely defining the cerebellum - they are including the CSF of the sulci. Therefore I am trying to work through sensible options for refining the segmentations and I thought that one of those could be altering the boundary correction option.
I know that fast is the preferred method of boundary correction for the cerebellum, but I thought I would try the thresh option and see how it affects the segmentations. However, if it is not recommended I might try to think of other options for improving the outline. Thanks for clarifying it for me.
Kind regards,
Clare
