Sulcal Depth from FreeSurfer Output

Hi there,

I am struggling to calculate sulcal depth using FreeSurfer recon-all outputs for a set of subjects so that I can obtain the same metrics as the ABCD dataset (Structural Magnetic Resonance Imaging → sulcal depth Fischl, et al., 1999a).

I calculate area, volume, and thickness for the destrieux atlas for example, using aparcstats2table and asegstats2table for subcortical structures. I have been trying to use the mris_curvature_stats and mris_anatomical_stats commands to get sulcal depth with no success.

I can’t find it in the ABCD release notes or other documentation about how they did this.

Thank you so much for reading!
