Hi all. After looking over our monte-carlo results, I a simple question about the sig.cluster.summary output.
Is the " Max" in column 2 below a measurement of thickness? If it is thickness, is the correct interpretation the following: the most significant cluster is in the laterorbitofrontal region. The max vertex in that cluster has an average thickness of 3.312 mm and the negative directionality indicates that it is thinner in that region than in the fsaverage (from freesufer) used in the group analysis/simulations?
If it does not refer to thickness, is it a statistic, etc?

I am trying to finish writing up my results and just need answer to this question to continue.
