Well, I'm dealing with a patient with an heterogeneous lesion. Somehow, the lesion area seems to have misled the algorithm in terms of white and pial surface definition, leading to an erroneous cortical thickness measure in that area. What I was interested in analising (if possible) is the dispersion related to the thickness measures in that area.

what exactly do you mean? Spatial standard deviations? Usually those aren't
terribly interesting, and it's the cross subject ones that are more
useful, but that doesn't sound like what you mean.
