Dear Doug and Freesurfer experts,

I have a question related to the previous post. I have two groups
(patients and controls), for which I have both functional and T1 data.
I'd like to look at differences in cortical thickness between the groups
inside some clusters of functional activation. 
Would it be wrong to overlay the activations (spmT.img maps) on
fsaverage, convert them into labels (through Fill Stats) and use
label2label to map them to each subject's surface?

Thanks very much!
Irene
