There is nothing to fit nonlinear parameters. You can do some simpling
things. Eg, if you believe that thickness is changing exponentially with
time, th = exp(-a/t), then you can take the log of the thickness so that
log(th) = -a/t, then fit for a.

I was wondering if there's a method to examine non-linear correlations in
FreeSurfer. Specifically, I'd like to use a behavioural correlate and see
if there are any correlations in the cortex. The linear correlation wasn't
as fruitful as I'd hoped, but there is evidence that a
