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.
