3dlme interaction term

We have resting state fmri data from group (groupA, groupB) and time (T1, T2).
We want to test interactions between group x time, but test specific interactions, e.g., signifant time effect in groupA, but not in groupB, using 3dLME.
I am wondering how I am able to test such specific patterns of interactions and how I can use glt code in 3dLME.

Any helps would be appreciated!



If you don’t have missing data, it might be easier to use 3dMVM.

time effect in groupA, but not in groupB

Try something like

-gltCode … ‘group : 1groupA time : 1T1 -1*T2’
