[gmx-users] SO4 ion

[simon sham]

Hi,
I have a crystal structure with several SO4 ions.
According to the online manual, the source is ffgmx.rtp. But I could not find it in 
/gromacs/share/top directory. I also could not find it in several force field files.

Just curious how people have treated this ion in their simulations.

Thanks for your help.

Simon Sham
