External Email - Use Caution        

Hello,

I wanted to compare the results of the aparc.stats on the same subjects when only the T1 is used and when T2 is used for pial refinement along with the same T1. To my surprise the tickness increased (on average across regions), the gm volume decreased and the surface didnt change. My questions is how is that the thickness increased and the volume decresed if the surface did not change?

(I used freesrufer 7.1.1)

Many thanks,

Gonzalo.
