Hello Dr. Foley,

Thank you for your feedback. If I may ask, is that due to the rising nature of rmsd or rapid fluctuations of the points?

I would not consider the system in that image to be equilibrated.

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.
