Hi Everybody,
has anyone tried to run namd 2.7b2 or later with amber force field (in
amber prmtop format) lately?
For a large variety of systems (solvated/unsolvated,
periodic/non-periodic) and machines I keep getting a segementation fault
during the startup phase. See bellow.
Versions 2.6 or 2.7b1 do not cause this problem.
Thanks in advance for any tip,
George
