Thanks Mark. Yes, my ligand.itp indeed has both [atomtypes] entry as well
as [molecule] entry. I have followed the following procedure to #include
while creating my first molecule:
Run pdb2gmx command.
Added #include ligand.itp after
#include charmm27.ff/forcefield.itp
but before
[ moleculetype ]

To test swiss param parameters, I have generated *.pdb and *.itp files from

I have included *.itp in the topology as:
; Include Position restraint file

Probably you will see that your ligand.itp has an [atomtypes] entry as well
as a [molecule] entry, and the former cannot follow any instance of the
latter. Such an .itp file must be #included to create the first molecule.
You have your protein [molecule] above the #include ligand.itp at the
Dear all
I am trying to simulate a protein in 3 steps: energy minimization (using
em.mdp), position restraints (using pr.mdp) and final production run by NPT
ensemble (using full.mdp) at 300K
At this temperature, it is known by previous literature survey that protein
keeps its secondary
Seems like you're using cut-off electrostatics, which would be a good way
of picking lottery numbers, and that's about all.
