Hi Amy,
You need to set up your path, and probably just logout
and log back on when done (least confusing way to go).
There is no reason to include 'exit' after running afni,
that just terminates your terminal process.
Have you set up your path? Actually, you seem to have
an extra level of abin, as you are running:
~/abin/abin/afni, rather than just ~/abin/afni.
What is the output from:
~/abin/abin/afni_system_check.py -check_all
If you prefer, you can sent that via email.
