cpptraj is lots better than ptraj for this.

I don't understand the distinction you are trying to draw: different people
will define the term "hydrogen bond length" in different ways. Beyond that,
in ptraj there are two "acceptor" atoms, and one "donor".
But it's easy for you to figure this out for yourself: do a "one-frame"
calculation, and compare the distance ptraj prints out with the actual
distance in the structure. This is the only way that you can be sure you
understand what ptraj is doing.
....good luck...dac
