Make sure you examine the above warnings: they may well be errors in your
case.

This means that your PDB file is missing an atom named "C135" in
residue 1 named GRA. This might be OK if that is what you expect, but be
aware that LEaP may build this atom in a non-optimal position.

Obviously, you should check to see if these warnings are expected.

It doesn't look like you ever loaded the frcmod file that parmchk created.
You need to invoke the loadAmberParams command to do that. Also, you should
use parmchk and not parmchk2, although I don't think that is an issue here.
