[gmx-users] gromacs (4.5) installation problem

[Moeed]

Dear experts,

I have installed newest version of gromacs (4.5) on our cluster. When I
issue the command below to test installation I get an error about atom type
CU+2. I am not using such atom type at all! Could you please help me what
wrong is. Thanks.

My system contains only C and H atoms!. Force field: OPLSAA


grompp -f *.mdp -c *.gro -p *.top -o out >& output.grompp_md

NOTE 1 [file md-NVT-revised.mdp]:
 nstcomm < nstcalcenergy defeats the purpose of nstcalcenergy, setting
 nstcomm to nstcalcenergy
