Thank you for your reply, I was intended to seen the difference in
molecular movement of my protein upon mutation. My protein is a GTPase
protein and I have done simulation in presence of GTP, GDP and GDP+Pi
for both the wild type and the mutated protein. Then I have done
principle component analysis and RMSD & RMSF comparison of the
trajectories. Now I want to check the authenticity of the set of
simulation and whether they can be reproduce to validate my results.
Please kindly help me in this regard.
