Hi Michael,
Yes, uber_subject.py is more of an introductory tool
to get started with afni_proc.py, and will almost
certainly never have the flexibility of afni_proc.py.
Using afni_proc.py does not mean generating a script
from scratch though. There are lots of examples,
and uber_subject.py can be used to generate an AP
command that you further modify to suit your needs.
Yes, when uber_subject.py opens the afni_proc.py
command window, one can alter that script. That may
not be a good long term way to go, but it works.
