[gmx-users] HELP - Fatal error gmx pdb2gmx

[Edjan Silva]

I deleted all non-protein molecules and saved the file. I typed the
following command:

*gmx pdb2gmx -f 4gy7.pdb -o conf.gro -ignh*

The error was as follows:

*Fatal error:*
*The residues in the chain MET1--PHE840 do not have a consistent type. The*
*first residue has type 'Protein', while residue CME59 is of type 'Other'.*
*Either there is a mistake in your chain, or it includes nonstandard
residue*
*names that have not yet been added to the residuetypes.dat file in the
GROMACS*
*library directory. If there are other molecules such as ligands, they
should*
*not have the same chain ID as the adjacent protein chain since it's a
separate*
*molecule.*

*For more information and tips for troubleshooting, please check the
GROMACS*
*website at http://www.gromacs.org/Documentation/Errors

I could not run the command without problem. What should I do?
