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
