I think the right way is to weight by the area, but for those 3 I bet it
makes almost no difference.

Dear FreeSurfers,
suppose I should estimate the mean cortical thickness on a number N of
ROIs (for instance, the left inferior temporal, the left
middletemporal, and the left superior temporal). How would you suggest
me to proceed?
- Just performing a simple average of the 3 cortical thickness values
obtained with the aparcstats2table?
- Computing a weighted average of the 3 cortical thickness values
obtained with the aparcstats2table? In this case, what would you use
as weight? The area of the 3 regions?
Thank you.
Best,
Elisa
