Dear gmx users,
I've installed the gromacs version 4.5.5 on my laptop. But the version of gromacs on the cluster, which I want to run MD, is 4.0. First of all. is it possible that I use this one?
Secondly, when I run this command, I get a fatal error as below:

# grompp -f md.mdp -c npt.gro -t npt.cpt -p popc.top -o md.tpr
 Fatal error:
Invalid dihedral type 9 

Is it because of the differences between versions?

Thanks in advance,
