I also think that this common task should be
implemented, but I can't find it... Probably somebody
know how to do it effectively - it's really tiring to
shift the coordinates with the Perl script.

Sure, I did energy minimization first and it ran
without problems. But after that I always have this
"30 deg" warning in the unrestrained run...

The topology is correct. I did flavone in vacuum and
flavone in water - it's Ok.
As far as I know "30 deg" warning is mostly due to the
polar molecule (water?) trapped in the non-polar
region, but I don't have water in the membrane! Any suggestions?
