You can either use -ighn option in pdb2gmx or mannualy rename the atom names in 
the pdb file.

Cheers,

Subject: [gmx-users] how to handle different atom names between pdb and rtp 
files.

 
Hello, I’ve got a pdb file,but while I convert it to gro files, I met such 
problem:
 
Atom HA in residue MET 1 was not found in rtp entry MET with 11 atoms while 
sorting atoms
 
I find that in the rtp files of the ff files, the H atom linked with C-alpha is 
called H, but in the pdb file, the same hydrogen atom is called HA, I think this 
may be the problem. 

 
So, my problem is, how to convert my pdb files to make the atom names consistent 
between the pdb and rtp files?
