Hi Mark,

Thanks for your reply!

I want to use the pre-saved trajectory.  Based on the distance criteria,
calculate the Coulomb and LJ interaction. However, I don't know the data
structure related with the LJ parameters. Do you have related knowledge?

The pairlist construction makes all this fairly messy. If you can do it with -rerun, do it.

The mdrun -rerun might be impossible for me, because I want to calculate
the energy terms based on the distance, which is not the cutoff distance
in the simulations, but one from RDF calculation.

That's fine. You can do mdrun -rerun with a .tpr that encodes a distinct model physics from one that made the simulation - that's one thing it is for. Thus you can pick your LJ model at will.
