Hi Jon, QDEC does not currently allow more than one covariates of interest. You will have to use the command-line stream (ie, mris_preproc, mri_surf2surf, mri_glmfit, mri_glmfit-sim)

HI freesurfer experts
I want to do an analysis in qdec with 2 groups(ADHD, and Marijuana usage) and 2 covariates(age and gender) to study the effect of these factors on cortical thickness. I can only select a covariate in the qdec gui. is there a way to select both covariates in the qdec GUI? Thanks Jon
