[gmx-users] Using FFTK generated parameter file for Protein-Ligand simulations

[Soumya Lipsa Rath]

Dear Gromacs Users,

I have to run a protein-ligand system. I am using CHARMM36 ff for the
simulation. For generating the parameters for the ligand molecule I used
the forcefield development toolkit of vmd, which gives CHARMM compatible
parameters.

But, I am unable to understand how should I include the parameters I had
obtained. I went through the tutorial files which shows an example of
PRODRG server for generating the itp file, but my ligand contains metal
atoms. I would appreciate if somebody could suggest me how to solve this.

Thanks,
Soumya
