[gmx-users] amber force field ff12SB and ff14SB for gromacs uploaded

[Alexey Shvetsov]

Hi!

Thank you forforcefield conversion! But how you checked that all 
energies are same?

PS problems with different ions can be simply fixed with set of defines
PPS also seems like forcefield.doc in ff directory are wrong. It states 
that it is still amber99sb forcefield
