[gmx-users] "No default proper Dih.type

[varsha gautham]

Dear all,

Am trying to do simulation of DPPC membrane.Am using ffgmx force
field,because other force fields doesnt have DPP residue,so got an error
saying "Residue DPP not in topology database.

So i generated topology file using pdb2gmx -ff gmx -f inp.pdb -o out.gro

now after few more steps i updated topology again to run grompp..

on grompp am getting an error saying
