Thanks to both of you. I tried doing -visual, but I don't know how to use the information I got from watching the process. I don't think stopping early (if there's a way to do that) would have helped much, either, because the problem spot became a problem before the rest of the mask stabilized. I will be experimenting.

Also, while I was playing around trying to find a way to preprocess the anatomical to make the dura darker, I noticed that sometimes the final mask extends outside of the final surface while remaining inside its convex hull:

I've noticed this before in the superior sagittal sinus of normal datasets, but it's more pronounced here. Is this intentional? (Don't mind the poor fit of the surface itself-- that's the preprocessing's fault)

EDIT: The preprocessing in question was an attempt to suppress areas with a lot of variation that's not due to edges, since GM and WM are each quite homogeneous, but with sharp edges between, but dura looks a lot noisier. Are there ways to measure that?
