Hello sir As in the tutorial for umbrella sampling command
make_ndx -f npt.gro you have selected two different groups as Chain_A as 19 and Chain_B as 20 If we have protein-ligand interaction whether we should have single group of protein-ligand complex or we should use two different groups for protein and ligand.
