[Freesurfer] FreeSurfer : About ROI analysis

Hello,

As a PhD student, I often use Freesurfer software and more precisely QDEC. A great question arises in connection with my last work. After drawing ROIs, I extricated values thanks to a " .levels" and a creation of a "stat" folder for each participant (aparcstat2table).

My question is : can I make a correlation between a behavioral score and the value of "average SURFACE" obtained for each participant thanks to the command above-mentioned considering that my ROI has been drawn from clusters detected with a correlational analysis between THICKNESS (and not surface) and a behavioral score on QDEC ?

Many thanks in advance for your assistance, and I am looking forward to hearing from you.
