Hi,
You'll learn a lot more, and have confidence that you are getting what you

Dear Justin and David,
Thanks for your replies. So as I understand from your answers, I need to
put the sigma and epsilon for my atomtypes (without any conversions) under
the C6 and C12 columns in ffnonbonded.itp and these numbers will be
interpreted as sigma and epsilon when I specify the

Please clarify these following doubts regarding combination rules in gromos
force field:
1. The ffnonbonded.itp contains c6, c12 terms. If I choose combination rule
1 , it takes V and W as C6 and C12 as given. If combination 2 or 3 are
chosen ,
