[gmx-users] problem during converting ".pdb" to ".gro"

[Moutusi Manna]

         I want to perform simulation of
trans-membrane
peptide. I have a equilibrated POPC (hydrated)
bilayer (using CHARMM),containing more than 32,000
atom. But when I try to convert ".pdb" to ".gro" using
"pdb2gmx", it shows the following error


Fatal error:
Residue "popc" not found in residue topology database

Please suggest how I can overcome this problem .
