If you have a recent version, you can use the command-line program
--version show program's version number and exit
-h, --help show this help message and exit
--show-defaults Display defaults
to get the files needed for phenix.refine. Don't make a "super
residue" as I believe that will make life difficult when you try to
deposit to the PDB.
PS. Happy to help you directly if you have issues.
