Hello,

I am needing to include a single hydroxide ion in my simulation - is there a force field available in Gromacs that is already parameterized, or do I need to create from scratch? With regards to topology, same question, especially as PRODRG does not do mono or diatomics. Any guidance anyone could provide would be very much appreciated. I have tried searching the archives but didn't find anything.


No, you'll need to do it yourself. The topology should be trivial - two atoms, one bond. As for what parameters to assign, there you've got your work cut out for you.

Thanks Marc Charendoff
