Hi Mark,
Thanks for that - it is really helpful. I see that the thresh option won't really have been useful here. The images give me more of a feel for what level of detail is possible and the segmentations are actually pretty good once I take into account the complexity of the structure and the high degree of partial volume. I might try masking the cerebellum segmentations with the FAST segmentation and see how much it helps as I have already run FAST on some of the scans.
Thanks for all your help.
All the best,
Clare
