Dear Freesurfer,

I am new to freesurfer and have a number of beginner's questions. After recon all the subjects and running the freesurferstats2table script, I am looking at the two files: aparc_area_lh.txt and aparc_meancurv_lh.txt. Everything goes by default.

My questions are,

1. In the aparc_area_lh.txt, is the surface area based on the pial surface, the white surface, or both?

2. In the aparc_meancurv_lh.txt, is it based on the Gaussian Curvature of the white surface or the pial surface?

I cannot find the relevant documentation in the freesurfer wiki. Any comments are highly appreciated!

Best Regards,

Daniel
