Dear all,

I am using DMPC lipid bilayer from teleman sir website to insert my protein in this lipid bilayer .I have done this by using command genbox. After that when I have run the command - pdb2gmx -f tap-in-dmpc.pdb -o tap-in-dmpc.gro -p tap-in-dmpc.top -i tap-in-dmpc-itp -ff oplsaa

Error like this-

There are 0 hydrogen bonds
Warning: 'DMP' not found in residue topology database, trying to use 'DMSO'

-------------------------------------------------------
Program pdb2gmx, VERSION 4.0.3
Source code file: pdb2gmx.c, line: 429

Fatal error:
Atom C1 in residue DMSO 1 not found in rtp entry with 10 atoms
             while sorting atoms
-------------------------------------------------------
so please tell me how can I add DMP in residue topology database if anyone has knowledge about this. And please if also u know about any site of lipid bilayer from where i can download lipid bilayer then let me know.
