[gmx-users] RMSD plots protein-protein complex

Hello
I did a simulation of protein-protein interaction with Gromacs code. In
this simulation, the number of amino acids in each protein is about 230.
The simulation production run was 300ns. After analyzing trajectory, I
found that RMSD value of protein-protein complex fluctuated near 1.8 nm but
the single of each protein has RMSD plots around 0.35 nm. Other plots (rg ,
rmsf) of the protein-protein complex show my complex system is stable. But
I have a problem with the RMSD value (not behavior) of mix proteins. Is it
normal?
