This sounds like an error that I've already fixed, but I can't recall for
sure. Can you send me, off-list, a compressed tarball containing the
topology files, input file, and a trajectory with 2 frames? (You can use
cpptraj to extract 2 frames).
I will try to have a look and see if I can reproduce the error.
Thanks,
Jason
