[Freesurfer] Reporting Cohen's D for a significant cluster

Dear Experts,

I was requested to report the Cohen’s D value for a significant cluster, which resulted from a cortical thickness analysis. I was able to calculate it and open the resulting Cohen’s D mgh file in Freeview, together with the file, indicating a significant cluster. As expected, when I move the cursor within the significant cluster, Cohen’s D value changes with every vertex. I was wondering if you might have any recommendations for which of the Cohen’s D values to report, and how best to obtain that value?

Thank you for your help, arkadiy
