Gert, There is nothing wrong with suggesting 45 softwares, as one of those may do exactly what a person needs and save loads of time. Besides, comparing protein structures locally need not involve any superposition method. I would say comparing torsion angles/distances between atoms is a mor

I had success once by varying the drop volume ratios as described here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2203341/ although we ended up getting data from a different crystal form. ~1 M LiSO4 is a surprising condition for cocrystallizing protein and DNA if they aren't covalently or topol
