Success rate as a function
of N-ranked models
considered based on the HADDOCK score (top N) for
tops 1, 5, 10, 50, 100, 200, and 1000 models for the initial rigid-body
docking (it0) and after flexible refinement (it1). Each stacked bar
plot corresponds to a specific cutoff with the color of the bar indicating
the distribution of model quality for that cutoff. Dark green, light
green, light blue, and light grey correspond to high-, medium-, acceptable-,
and near-acceptable-quality models, respectively. The respective RMSD
cutoffs are ≤0.5, ≤1, ≤2, and ≤2.5 Å
when considering all heavy atoms of the compound after superimposing
on the binding site backbone atoms of the receptors. Results have
been grouped by protocol on the y axis and stage
on the x axis. The black vertical line in the “it0”
indicates the cutoff at which models proceed to flexible refinement.
