[gmx-users] editbox removes dummy atoms

[reisingere at rostlab.informatik.tu-muenchen.de]

I have found out that there was always the same residue number for all the
dummy atoms. Perhaps that was the failure. Now I changed it so that they
have all different residue numbers. But now I get the error:

Atom N is used in an interaction of type improper in the topology
database, but an atom of that name was not found in residue
number 309.

when I want to put hydrogens to the structure.
