Hello FS experts,

 

I have a cohort of subjects for whom I created cortical thickness and T1w/T2w signal ratio surface maps, projected them to fsaverage’s surface, smoothed them, and then created average thickness and T1w/T2w maps using mris_preproc. Is there a way to statistically compare the two averaged surface maps (i.e., come up with a third surface map displaying correlation patterns between thickness and T1w/T2w signal across the surface)?  

 

Thanks in advance!

 

Best,

Panos
