You'd better first your .top file, to see if you have included DPPC .itp file and also in the compound section. if it was ok, check the .ndx and look for the atom numbers of DPPC, after finding the atom numbers, make a group ( Like othe parts of .ndx; water, or protein,...) and name it DPPC. save and continue. Hope it help

Subject: [gmx-users] problem with volume equilibration
When I run the command (i.e., grompp -f nvt.mdp -c em.gro -p topol.top -n index.ndx -o nvt.tpr)for volume equilibration.
I am getting the error:
Group DPPC not found in indexfile.
Maybe you have non-default goups in your mdp file, while not using the '-n' option of grompp.
In that case use the '-n' option.
Please guide me.
