Hello, You have to look into your ions.itp which is included in your top-file by #include ions.itp. There all the types of ions have to be defined. The atom-types which you can see in the ions.itp, you will find in the ff"your-forcefield".itp where your atomtypes are defined. On top of your .top f

Serdar. If the "real charge" of your system is not zero and you are using PME, then PME code will take account for any non-zero charge on the system and neutralize it with an uniform background charge ( http://wiki.gromacs.org/index.php/Errors). If your system is composed by a protein, then try fi

Sometimes when grompp reports the total charge, it shows up as a non-integer and can sometimes be attributed to a round-off error. Just to be sure, check your topology to make sure you have integer charges on all components of your system. -Justin serdar durdagi wrote: Dear all, In one o
