I have tested a simulation of a single ethanediol in a
periodic box, with the starting configuration appropriate
for an internal H bond formation, and everything were fine.
The oxygens remained far apart, and the hydroxils bond streaching
I don't know what is going on with the carbohydrate simulation.
