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

Update: It occurred to me that reporting it for the max verted might be the best idea. In this case, might anyone know what is the best way to navigate the Freeview to a specific vertex number (is there a place where I can input that number). Thanks again.

Hi Arkadiy
if you have the surface loaded you can always type a vertex number into the info field (that shows the current selected vertex) at the bottom of the freeview window. It will then jump to that vertex, and adjust the views accordingly
