Dear Gromacs Users or Developers, I am using the pulling the COM of object A towards B using: --------------------------------- pull = umbrella pull_geometry = distance pull_dim = N N Y pull_start = yes pull_ngroups = 1 pull_group0 = B pull_group1 = A pull_rate1 = -0.00005714 pull_k1 = 5000 ------------------------------- On the output file of pullx.xvg, the sign of dZ has been changed from negative to posivitve or vice vrsa in all sudden. What does it mean?
The following is an example: @ title "Pull COM" @ xaxis label "Time (ps)" @ yaxis label "Position (nm)" @TYPE xy @ view 0.15, 0.15, 0.75, 0.85 @ legend on @ legend box on @ legend loctype view @ legend 0.78, 0.8 @ legend length 2 @ s0 legend "0 Z" @ s1 legend "1 dZ" --------------------------------------------------- 173.7400 0.77622 8.14856 173.7500 0.77622 8.14897 173.7600 0.77622 8.14938 173.7700 0.77622 8.14977 173.7800 0.77622 -8.14987 173.7900 0.77622 -8.14954 173.8000 0.77622 -8.14924 173.8100 0.77622 -8.14895 ------------------------------------ Thanks a lot for the information!
