You can replace all of this with the single command:
autoimage
What you have now seems like overkill, especially the last one. Before
autoimage, I would center the first molecule (or monomer, assuming you have
multiple, disconnected subunits), image everything around that first
monomer, then center and image again around the rest of the solute (the
solvent will take care of itself). In the case of DNA, unless it is some
sort of single-stranded loop, that means centering and imaging the first
strand, then centering and imaging both strands.
