Re: [AMBER] Incosistency in energy values from out files and cpptraj energy tools

For historical reasons, the energies printed to MDOUT are 1 time step
ahead of the coordinates (see e.g. If you do energy
post-processing with sander (i.e. imin=5) on that trajectory then the
energies should match exactly (assuming you're using the same cutoffs,
ewald parameters, etc).

I did a 3ns equilibration run on my system and I observe that the energy values for the last frame in out file (last_frame_energy.dat attached) do not match the energy values obtained from cpptraj energy tool by taking the restart file as input (cpptraj_energy.dat attached). I cannot understand why this is happening. Any sort of help would be appreciated!
