martinize is written to coarse grain proteins (and nucleic acids). It just
can't generate a topology for coarse grained structure, which is a quite
different problem. I'm also not exactly sure what increasing by one 'unit'
means. One residue, one molecule, one copy of a system? If it's about
adding molecules, you can simply use the itp for one unit and specify in
the .top file you'll have more of that molecule. If it's something else you
need, please be more specific about what you're trying to do.
