[gmx-users] non-matching atom names

[abhisek Mondal]

Hi,

I'm getting an unusual warning whenever I execute *$ grompp -f em.mdp -c
solv.gro -p topol.top -o ions.tpr *
saying:


*Warning: atom name 4687 in topol.top and solv.gro does not match (C1B -
N7N)*
*.....*
*......*
*WARNING 1 [file topol.top, line 44227]:*
*  71 non-matching atom names*
*  atom names from topol.top will be used*
*  atom names from solv.gro will be ignored*

I'm having a protein ligand system, where topology of ligand (*ligand.itp*)
is generated from CGenFF and *ligand.gro* (for building the *complex.gro*) file
was obtained from PRODRG server.

Please suggest me a way out of this.

Thank you.
