Hi Agent 007 -

That seems right.

In this case, it makes sense if your model contains the interaction term between Group and outcome1.

> -gltCode outcome1_T4 'outcome1 : Time :4' \

You're not modeling the interaction between Time and outcome1. So, if I interpret what you want correctly, just do

-gltCode outcome1_T4 'outcome1 :' \

> -gltCode outcome1_G1_T4 'Group: 1*Group1 outcome1 : Time :4' \

Same as above

> -gltCode outcome1_over_time 'outcome1 : Time :' \
> -gltCode outcome1_G1_over_time 'Group: 1*Group1 outcome1 : Time :' \
> -gltCode outcome1_GroupDiff_over_time 'Group: 1*Group1 -1*Group2 outcome1 : Time :' \

These three lines don't make sense to me. Could you explain what are you exactly looking for?
