Hello Freesurfer team, I am using an annotation file that i've created previously to obtain the measures of some ROIs. To do that i am using de commands mri_surf2surf and mri_segstats. I want to obtain the following measures:

1. Gray and White Matter Volume

2. Folding Index

3. Curvature measures

4. Thickness

However I don't know what surface in the surf folder of each subject I have to use. Could u help me?
