[gmx-users] Problem running equilibration step

I am doing simulation of DNA nano-structure using Gromacs (VERSION 4.6.5)
by applying CHARMM26 force field and TIP4P water model. The energy
minimization step is working fine but i am facing problem during
equilibration step due to wrong *nvt.mdp* file.
Can you please guide me, which kind of parameter should be change in
*nvt.mdp* file for DNA nano-structure MD simulation. I am following Justin
A. Lemkul's tutorial (Lysozyme in water) using following link;
I am getting error like this;
318 atoms are not part of any of the T-Coupling groups
My command line is like this;
*grompp -f nvt.mdp -c em.gro -p topol.top -o nvt.tpr *
I am also attaching the modified nvt.mdp file according to DNA MD
simulation requirement for your reference.
I am working under the government organization, National center for Cell
Science meant for non-profit research. I shall be highly obliged if you
could help me to solve this problem.
