Re: AMBER: What does this error message mean?

This is a typical problem in the setup of the system. The message refers
to atoms 1427 1428 (distance between them is larger than the one expected
from the topology file --> and then SHAKE procedure is the first thing
that crashes). To solve this (2 ideas):

i) look for consistency between your topology-coordinate files (same order
in the atoms)

ii) if consistency is OK, try minimizing your system (to avoid close
contacts between atoms) before starting a fully unrestrained MD.

Hope this helps
