right, qdec shows healthy (X) > patients (Y)
mris_anatomical_stats show: Y > X
but I didn't do mri_surf2surf, I just copied the ROI.label in every subjects /label/ directory.
Thank you for your help Doug !
Have a great day,
Alex.

blue means that X>Y. So that sounds like it is compatible with your ROI results, yes? doug

Dear Freesurfer Experts,
In qdec for question: "Does the average thickness differ between X and Y" we received blue colored regions, meaning that thickness for group Y is lower then X ?
We created ROIs for each region, and extracted cortical thickness for each ROI for each subject using mris_anatomical_stats.
in results: for each ROI, mean cortical thickness of Y group are higher then X.
is it a mistake, or the question was misunderstood ?
Sincerely, Alex.
