Thanks Doug,
That seem to work for some of my variables (e.g. depression) when I put gender and diagnosis as fixed factors, depression as covariate, and age as nuisance factor but not for others (e.g. anxiety). I keep getting error messages when trying to run some of my variables as covariates (please see attached). Is there anything I can do to fix this?
Thanks, Jen

Just include it as a categorical factor. When you look at your contrast of interest, it will be with respect to regressing out gender

Hi Freesurfer experts,
I am trying to compare cortical thickness between groups while controlling for age and gender using QDEC. However, _gender_ is not showing up as a covariate variable or a nuisance factor (only showing up as a fixed factor), I am wondering how I could control for gender in this case?
Thank you very much,
Jen
