Dear GROMACS users,
I have been trying to set up a simulation system containing 4 Hypericin
molecules in a box of water.
When I'm trying to run energy minimization,I get this error:

There were 8 warnings
I generated the topology file using acpype,after that with BallView copied the
hypericin molecules 4 times and saved to a pdb file.
In the topology file I made changes so that in [molecules] part,HYP1 was 4
(nmols) and for forcefield I included 1. #include
"amber99sb.ff/forcefield.itp" , 2.#include "HYP1_GMX.itp" and then #include
"amber99sb.ff/tip3p.itp".
I didn't have any problems with setting up the system with one molecule of
Hypericin and water box.So what was my mistake?
I need your help
Thanks in advance
