Hi folks,

I tried to extract the thickness/volume value of the ROI labels transferred from the annot files that're generated automatically by FreeSurfer after a succesful group analysis with corrected significant results. However, the thickness/volume values are no longer correlated with the independent variable that I used in the group analysis model earlier and even the direction of group difference seems to be inconsistent with the group analysis results as well. I have no idea how it went wrong and wondered maybe  there's something wrong with my scripts. Have any of you run into such kind of problem? 

My script for ROI value extraction goes like this:
   
#annot2label:
mri_annotation2label --subject fsaverage --annotation onsetage_thickness --hemi rh --labelbase /expdata/wangyunxin/reconall_lj/fsaverage/labels/onsetage_thickness 

for i in sub*
do
#label2label:
mri_label2label --srclabel fsaverage/labels/onsetage_thickness-001.label --srcsubject fsaverage --trglabel ./$i/labels/onsetage_thickness-001.label --trgsubject $i --regmethod surface --hemi rh
#label2stats:
mris_anatomical_stats -l $i/labels/onsetage_thickness-001.label -t $i/surf/rh.thickness -f $i/stats/rh.onsetage_thickness-001.stats -nsmooth 10 $i rh
done

#stats2table
aparcstats2table --subjectsfile /expdata/wangyunxin/reconall_lj/music/sublist48 --hemi rh --meas thickness --parc onsetage_thickness-001 --tablefile music/onsetage_thickness-001_rh.txt

Any suggestion would be great! 
Thanks!

Best,
Yunxin
