Hi Michelle,

those aren't necessarily problems. We see this in lower quality scans 
where you get little 1d protruberances that have very small radius of 
curvature. Have you checked the ?h.white surface in those locations? At the 
end of the day, that's what you really care about. If you don't like them 
in your overlay for visualization purposes you could smooth the curvature a 
bit (tksurfer tools->surface->smooth curvature

cheers
Bruce
