I'm not sure what you mean. do you have a behavioral value (eg, reaction time) for each stimulus presentation? If so, you'll want to do a parametric modulation https://surfer.nmr.mgh.harvard.edu/fswiki/FsFastParametricModulation

Hi Freesurfer experts,

I'd like to generate a correlation map showing the strength of correlation between a behavioral value and the value of a functional contrast between two conditions.

...

From previous cortical thickness analysis, I know that if I use the

-notask tag on mkanalysis, I can use a file that includes all of my behavioral values and correlate them with, say, a thickness value.

But when I use -notask, I can't specify a paradigm file, without which I can't specify contrasts. Is there a way to make this correlation map versus a functional value drawn from a contrast? This seems simple, conceptually, but I haven't been able to implement it.

Thanks in Advance, Joe
