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?

Yes

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?

It is the mean over all vertices without regard to structure doug
