Comparisons between the three models for RMSD. Model 1 (blue asterisk) use a gradient minimisation on each rotamer when it is placed (this paper's method); model 2 (red solid box) packs using the same method as model 1, but then after the fact, runs a global minimisation on the side chains at all packable positions; and model3 (green box) with normal rotamers is optimised by global minimisation.
