Gromacs-Molecular simulation of a protein and ligand

Question

[ashishajayan]

In gromacs after setting the forcefield, I get an error saying that my residue is not found in the topology database and thereby asked me to create a topology for the residue using the tool MKTOP. But it gives me an error saying that atom 1 has no conect. How do i proceed further?
