Hi Subha, yes, you can. You will need to create a table in the format with QDEC expects. Have you looked at the tutorial?

Hi, 
 
I am new to freesurfer. I have run reconall on 50 AD subjects. I have also run recon-all -qcache.
 
So I have the following -
 
1) Whole brain thickness map for each AD subject
2) age of each subject
3) gender of each subject
4) clinical score of each subject
 
I DO NOT have control subjects. 
 
I want to run a glm to investigate whether if there is a relation between the clinical score for each subject and their cortical thickness while accounting for age, gender and whole brain average thickness. 
 
Can I use qdec for this ? 
 
This is my first time doing this sort of analysis, so I will be grateful if I can get some step-by-step help. 
 
Thank you very much
 
Subha
