Is any one of you experienced with simulation of DNA in vacuum ? I tried
to simulate a 12bp strand but found that even at very low temperatures the
dna is not stable. I observe after 10ps that 8 of the initially 22 h-bonds
between the bases are broken and the whole double helix is deformed. One
base even stucks out of the cylinder. This is for T=1K !
I know that simulating DNA in vacuum has been a problem in the early years
of MD. Is this still the case with namd ?
