dear gromacs guys,

trying to do some simulations using gromacs i used pdb2gmx as the first step of all of my work.
i use the following command and the oplsaa forcefield.
pdb2gmx -ignh -missing -ff oplsaa -f $1 -o $1.gro -p $1.top

running the pdb2gmx program there always occurs the same warning message:

Opening library file /home/jlenz/bin/gromacs/share/gromacs/top/ffoplsaa.rtp
Opening library file /home/jlenz/bin/gromacs/share/gromacs/top/aminoacids.dat
WARNING: all CONECT records are ignored
Opening library file /home/jlenz/bin/gromacs/share/gromacs/top/xlateat.dat
26 out of 26 lines of xlateat.dat converted succesfully
All occupancies are one
.

.
How can i fix this warning ? i have no idea. and i want to have this warning fixed before i start the time consuming simulation parts.
if anyone has an idea, please be so kind and give me a yell.
otherwise i cannot go on with simulation.
thanks a lot and have a nice day.

for proteins it will work fine.
for anything else you will have to check your topology.

greetings
joern
