Hi Jernej I'll choose AMBER or CHARMM, because these two forcefields have a more reliable description of nucleic acids. In my experience, OPLS-aa and GROMOS do not seem to be able to produce stable simulations in the large time scale for nucleic acids systems. Best regards Paulo Netz 2015-02-0

Hi everyone! I would like to study a DNA-protein complex. The protein part is composed of aminoacids covalently attached to the DNA bases. Which force field would you recommend? Based on recent experience I was thinking of using either OPLS-aa or CHARMM. OPLS-aa would be the prefered choice becau
