Hi LI! I'm not particularly experienced with Amber, but I ran into this same issue. If you are running a simulation with ntb=0 it will do this because your protein or nucleic acid is "drifting" from it's original position and the program automatically re-centers it. Adding nscm = 0 in the input file solved the issue for me.

Dear AMBER users,

Would anyone be able to enlighten me on what does this line indicates in the output file?

Tried to Google but didn't get to anywhere.

RE_POSITION Moving by -0.111645 -0.200871 -0.094889

Thanks in advance.

Best regards,

Li Zhe
