​prmtop/inpcrd is still the standard (and we still use the tleap program
you wrote all those years ago to generate them ;)).

The format has been updated within the last decade or so, and there are
several tools out there to write prmtops. The spec at is still up-to-date (and there's a more
detailed version in the appendix of my dissertation on ResearchGate).

All the best,
