I am running with gromacs 4.0.5. I am trying to do gromacs tutorial for drug-enzyme complex. I did this tutorial step by step but when I used the grompp step befor the energy minimization </div><div class="im"><div>"grompp -f em.mdp -c trp_b4em.gro -p trp.top -o trp_em.tpr"</div>
</div><div>I found the following error:</div><div class="im"><div>-------------------------------------------------------</div><div>Program grompp, VERSION 4.0.5</div></div><div>Source code file: toppush.c, line: 947</div>
