Freesurfers-<div><br></div><div>Question, when looking for interactions to justify using DOSS say i am looking at cortical thickness and i have two discrete variables (G1 and G2) and 4 continious variables (V1, V2, V3, V4). My thinking is that i should look to see if there are interactions with the groups and each individual variable. However what if it is likely that an interaction of G1, G2, and V1 can be explained by V2?</div>
