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

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.

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 ?
Sincerely, Alex.

the easiest way to determine X from Y and blue from red (ie, which group is getting thicker or thinner) is to Ctrl-right click on a vertex within the region of interest on the cortex result display. a plot will appear showing the raw thickness values for your groups, and which-is-which should obvious.

Thank you very much for the idea Nick, this explained everything. In qdec red means X>Y
we didn't notice the thickness data on that plot at first :(
Have a wonderful week !
