Using alchembed could work in a couple of ways:
a = Alchembed(structure="input.gro", topology="input.top") a.add(structure="input2.gro", topology="input2.top") a.add(selection="resname POPC")
The big challenge here is understanding GROMACS moltypes. Let's look at how the Protein moltype works:

The final interface should work something like;
alchembed(simulation wrapper, input.gro, input.top, alchembed.mdp, molecule type, working directory )
Sorry, something went wrong.
