Hi Freesurfer experts,

I am interested in estimating mean curvature index for each of the 7 networks (Yeo7 atlas) for my data of healthy controls. I am able to estimate this subjectwise, and the output stats file for each subject looks like following:

I have 123 such files from a set of 123 subjects. I was just wondering how can I save mean curvature indices from all the subjects in one file (text or excel)? I defined my Subjects.txt file with subject IDs of each subject. I am not sure how to proceed from there to save curvature indices.

I tried to run following command, but that does not work:

aparcstats2table --subjectsfile Subjects.txt --hemi lh  --meas white.H -t MCI.txt

I would really appreciate any help.
