Re: [AMBER] Problem with MMPBSA.py

Hi Ray,
We reinstalled AmberTools 1.5 with all the bugfixes. The test suite passed
OK.
However, running MMPBSA.py I am getting an error:

PB Bomb in assignlvlset(): illegal insas flag 53 41 93 0

The PB section stops and MMPBSA continues next to calculate the normal
modes.

The input to the job and the script are the same as before (see below).

I might add that while in this system the error occurs always at the same
point, this error may not appear at all in a different trajectory or a
different system.
I hope someone could help.
Thanks very much,
Rami
