how to construct a topol file on graphene by using gromos54a7 forcefield?
Assuming we used gromos54a7 forcefield, not oplsaa forcefield.
I just constructed a topol file through building graphene.n2t file and using oplsaa forcefield below.
But I don't know how to construct a topol file by exploiting gromos54a7 forcefield.
thank you very much.
