WHAT IF validation. Each barplot displays a WHAT IF validation statistic for structure ensembles of different proteins, with bars representing the mean ± standard deviation computed from 20 structures. Structure calculations without any statistical torsion angle potential (black), with the DELPHIC potential¹² (gray), and with the new torsionDBPot potential (white) are included. Abbreviated protein names are used; for full names see Table II. Each statistic is a score: the larger the better. Packing quality (panel C) refers to the 2nd generation packing quality.
