[Freesurfer] Non-linear correlations

Hi Everyone,

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 non-linear relationship may exist. Is there any way of testing this?

Thanks.
