Yes, though I think it is the same as adding the Burden column.

Dear Doug,
Thank you for your instantaneous response!
Correcting for disease burden was actually a reviewer
comment.
We calculated mean
cortical thickness estimates for regions that showed vertex-wise age-related
cortical thickness differences between groups (using qdec) and then graphed out
you cannot do this in QDEC. In fact, it is a tricky analysis to do
properly. For each group you will need an offset regressor and an age
regressor, but only the patient group will have a burden regressor. This
cannot be done with an FSGD file either. You will have to create your
own design mat
Dear FreeSurfer Experts,
We are trying to run a between group analysis (1 patient
group 1 control group) within qdec. We are interested in investigating
age-related
thickness differences between groups. Our fixed factors are ‘group’ and our
continuous covariate is ‘age’. We
would like to contr
