[gmx-users] dummies and positional restraints

So you are sure you have included the restraints in the dummy topology.
What is the position restraint energy then?

If I saw it correclty you only restrain atoms 2,10 and 18.
Could it be that the dummy molecule is so flexible that it
could move a lot, even when the 3 restrained atoms do not move a lot?
