Hi Rick,
Thanks so much for your response.
This all seems reasonable. I'm going to give it a shot without using afni_proc.py. I've got scripts I use that essentially replicate that script, anyway. And, this will allow me to make important changes where needed.
One quick follow-up I have off the top of my head
What changes would you expect me to have to make to the motion params? I didn't even realize I could get access to those motion regressors. It makes sense to zero pad them just like the regressors of interest. Where do they live?
Thanks,
Adam
