Dear Doug and Freesurfers, I noticed that the DOSS option no longer exists in qdec and that Doug said there was a bug related to it. If i want to assess the differences in cortical thickness between groups while covariating for age and gender, since i don't expect any interactions, can i just demean the covariates and make my analysis in qdec with dods? Thanks!
Demeaning will not turn a DODS into a DOSS.
