Hi guys, 
 The error I'm getting is as follows
"All occupancies are one

Program pdb2gmx, VERSION 4.5.3
Source code file: resall.c, line: 581

Fatal error:
Residue 'DMP' not found in residue topology database
For more information and tips for troubleshooting, please check the GROMACS
website at http://www.gromacs.org/Documentation/Errors
-------------------------------------------------------"

And this is the command I used

pdb2gmx -f dmpc.pdb -o processed.gro -water spce -ignh

Force field : OPLS-AA/L all-atom force field (2001 aminoacid dihedrals)

Help me solve this.
Thanks and Regards
Santhosh.
