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
