Hello,
Before saying anything else, it has been years since I have run uber_subject.py on a mac. It might work, it might not.
Note that you are running python 3.7, yet PyQt4 was found for python 2.7. So it would be necessary to either install PyQt4 for python 3.7 (i.e. under /usr/local/lib/python3.7/site-packages), or use python 2.7 (which is hard to suggest, since it is no longer supported).
In any case, we highly suggest becoming more familiar with afni_proc.py directly, as uber_subject.py does not have interfaces for many of the more modern options in afni_proc.py.
