[Muthusankar]

Dear Gromacs users,
I am simulating a protein-ligand complex and performing the grompp command
before adding ions to the system. I got the error.
*Fatal error: *(file: ligand.itp)
Atomtype *CH2 not found*.
*command used:*
gmx grompp -f ions.mdp -c protein_box.gro -p protein.top -o ions.tpr

Please guide me, How to rectify the problem.
