That may be true, but does not mean that in all these force fields the parameters are good enough to assess 'real' behaviour of nucleic acids. E.g. the older GROMOS force fields (43a1, 43a2, 45a3) should not be used due to bad behaviour. Amber seems a good choice for Protein/DNA simulations. It's not the program/package that counts, it's the force field. Cheers, Tsjerk -- Tsjerk A.
