Hi,

I am looking at resting state connectivity with an amygdala ROI longitudinally and I want to see if amygdala connectivity changes with age (inverse,invcage). I am also including mean absolute motion displacement as a nuisance covariate (motion). I tried to set up the model as below, but 3dlme gets hung up and does not continue running. I think I am doing something incorrect with the nuisance covariate (motion)? I've already centered age prior to including it in the model. Do you have any suggestions on what I am doing wrong?

Thank you for your time!
Best, Maria
