[gmx-users] miscelle formation using ligands only

[Chetan Puri]

I am using gromacs for the first time . I have installed gromacs 5.0.4
version and i want to check a miscelle is formed or not using 5 different
 ligands in different ratios. I have gone through all basic tutorials on
how to use gromacs ( lysosyme,protein-ligand).

But i am stuck with the problem of having ligands only for simulation due
to no force field and topology file.
                      I have tried to use packmol to pack a cubic box with
all my different ligands in different ratios and generated a pdb file but
without making a topology file i am stuck.
          So if some one can suggest some possible ways  of doing it and i
don't have much computational background of manipulating various file
extensions of gromacs.
