Thank You Doug ! We created a specific label for each subject using cmd>
mri_label2label --srcsubject fsaverage --srclabel (the ROI.label created in qdec) --trgsubject SUBJECT_NAME --trglabel $SUBJECTS_DIR/SUBJECT_NAME/label/ROIx-lh.label --regmethod surface --hemi lh after that> mris_anatomical_stats -l (ROIx-lh.label address) -b SUBJECT_NAME lh the results are the same, qdec: X>Y mris: X<Y Did we miss another step again ?
