probably means your trajectory is not continuous enough. I saw the same thing when I try to fit an ensemble trajectory, which each frame is not from the previous one. Or if your first frame in your trajectory is not good looking(or having good rmsd to your target structure), fit option cannot fit

[gmx-users] sudden jumps in RMSD etc.

Hi all, I am doing duplicate MD simulations with a protein-ligand system. After processing one trajectory by trjconv with the optioin -pbc nojump, I still find abrupt jumps (on the scale of nm) in RMSDs and COM distances. Then I tried -pbc mol -ur compact, which did not work. And then -fit
