Subject: size of a simulation system

Hello everyone,

I am planning to run an MD simulation using Amber7 on a system of an
RNA-RNA complex including a total of 170 nts. With a water box, the
system includes a total of 721918 atoms. Is it practical to run a 5 ns MD
simulation on such a big system? Would the simulation results show any
significant movement as evidenced by some experiments? Do you have any
suggestions to obtain the dynamics of this RNA complex.

Thanks!
