Hi Hugo, they are assumed to be stationary. I've never tried to figure out how much of a problem this is.

Dear all,

I have been performing cortical thickness analyses and as far as I understand the thickness maps are non-stationary (please correct me if I'm wrong). I have two questions:
1. How susceptible is Monte Carlo clusterwise correction to this (should I expect clusters at smoother areas to be bigger?)?
2. Does FS perform some sort of correction to this non-stationarity or are images assumed to be stationary at statistical analyses?

Thanks a lot for your help!

Hugo
