SV: Re: [gmx-users] constraint distance

[Soren Enemark]

 Hi,
  maybe I am misunderstanding either the manual or the topic.. but - in my world -
  I never stop being puzzled by the part of chapt 6 in the manual which apparently
  says that such distance constraining is possible even though it (seems) to be
  secretly known that it is _not_ possible unless one uses the method suggested
  below.
  I believe, I suggest adding a comment in the manual.

The only way to get away with that is to merge your two parts to form
one molecule, with the only connection being a distance_restraint (or
another bonded term if you want to emulate bond-like behaviour such as
a salt-bridge).

Best,

Tsjerk
