the qdec tutorial describes how to draw a label on a region, and then map that label (roi) back to each subject. from there, aparcstats2table can be used to gather that roi data into a table for import into a stats program where you perform your analysis.

Dear all,
Hi, I am a new user of freesurfer, and have a questions on group analysis with qdec.
I compared average thickness between two groups (a control group and a patient group).
What I am trying to do next is to make a mask where the patient group showed reduction of cortical thickness (for example, p<0.05, FDR), then examine the correlation between clinical scales and cortical thickness in the masked regions, by doing group analysis in the regions (not entire brain).
I searched past archives, but couldn't find one. Does anyone know how to do this with qdec ?
Thanks for your help,
Kind regards
