Hi everybody,
I have simulated a DNA molecule for about 40ns and after analyzing the
trajectory what I got to know is that the two strands of DNA are going away
( I would say fluctuation of the double helix was observed) for a very
short interval of time and then they are again showing the usual double
helix structure. The backbone RMSD (after re-imaging the trajectory) with
the simulation length was observed as:

What could be the possible reason for this fluctuation. Is this fluctuation
indicates that the MD protocol is wrong? Please suggest.
Please let me know if some of the input/output files are required for
solving this problem.
Thanks and Regards,
Jac
