Hi Joern, Did you first perform an energy minimization in vacuum? The values you get indicate severe problems with your starting structure. By the way, for such a system you don't want to use a cubic box. It's an utter waste of resources. You're better off with a rhombic dodecahedron, or you can

dear users, i try to simulate a system of DNA (17 bp) and a protein (420 aa). before i start my MD runs, i solvated the system in a cubic box (-d = 0.9) and started a minimization of it using the em.mdp file which you can see at the bottom of this email. unfortunately the minimization breaks (se
