Hi, Petya-
OK, yes, I think it was just a matter of dealing with these files/variables:
/home/phoenix*/.bashrc:export PATH=$PATH:/home/petyakozhuharova/abin
/home/phoenix*/.cshrc:set path = ( $path /home/petyakozhuharova/abin )
... changing the location of abin to have your new username-- glad you have sorted it, then!
Note that you can also run the system check again:
afni_system_check.py -check_all
... just to be sure everything with the setup is happy.
