Thank you, Justin. I am trying to simulate a protein-ligand complex to see the conformation transition during the simulation... We propose that the receptor pocket may be subject to a conformational change upon ligand-binding, so I want to verify it by MD... I am really a newbie in molecular

Hi, I did a 70-ns MD simulation. I wonder how to justify when the trajectory reached equilibrium... Seen from RMSD-time curve of C-alpha, the curve reached about 1 nm at 12 ns and kept stable after that. Could I justify that the system reached equilibrium at 12 ns? Are there any
