I am getting output from t tests I specify in 3dMVM that I expect to be different from each other, but they are not, and I could use some help understanding why. There are a few variables in my model, but right now I would like to get a t test result for the within subject variable Drug for each sex separately. With the following 3dMVM script, the output from each glt line that I think should give me those separate tests (glt 2 and 3) yields datasets that are identical. I am not sure what i am doing wrong. Help?
