GROMACS version: 2021.3
GROMACS modification: No
I created index to join groups of interest for
gmx energy analysis. This requires a rerun from a
trr file. I noticed that this approach produces a new trajectory file so my guess is they have different
hash than the original trajectory. This must be because of the incorporation of index to the trajectory, but how about the positions and velocities of all atoms and molecules, are they entirely different? I am fine if its just within precision of error though.
