Dear Amber Users and Developers,
Here I have attached is a rmsd plot obtained for a ~100 ns equilibrated trajectory (saved at every 10 ps) of a DNA/ligand system. I am attempting to calculate absolute binding free energy through a thermodynamic integration (TI) approach. I was hoping if you could clarify to me whether the system is equilibrated enough to proceed with the TI calculations. I was under doubt due to the fluctuations shown throughout the last 6000 frames (60 ns). I understand there isn't an exact answer to this. But I appreciate your opinion on this.

Thank you
