Hi,
I am using FS v5.3 and I had two questions regarding the calculation of cortical thickness in the stats files:
1) Is the average cortical thickness of each structure (i.e. precuneus) calculated by averaging the cortical thickness values of each location in that structure?
2) Is the mean thickness calculated in the *h.aparc.stats (or in the other aparc stats files) calculated by averaging the cortical thickness values of all the structures in that hemisphere, or by using a weighted average of the cortical thicknesses of the structures included in that hemisphere?
Thanks, Panos
