Thanks Martin!. I have another quick question. I am also interested in looking at developmental changes in the brain during adolescence period in normal subjects and also comparing our controls to our clinical cohort. Examples in the longitudinal processing stream tutorial have only mentioned volu

Hi Yoon, I usually run mri_glmfit directly and then look at the gamma map (that is the average if you ran a one sample group mean analysis, which is what you did, I think). qdec is just a wrapper around glmfit so the file should be there, I am not sure if qdec can visualize it directly? (am no

Dear Freesurfers, Is there a way to visualize average absolute symmetrized percent thickness/volume/area change (not significance map) using qdec or tksurfer or other freesurfer tools? I successfully generated correlation significance map using qdec for the longitudinal data we processed, but I
