[gmx-users] FATAL ERROR Residue "LIG" not found in residue topology database?

Dear All usres: I am trying to do a simple system that contains 4 molecules ethane and MD run using GROMACS. I build my .pdb file by using Avogadro software . Afterwards, I try to generate the topology and .gro file using pdb2gmx program and it generates an error. I am using the 43a1 force field.
