WebFigure 5c shows that the mean length of chains built using phenix.map_to_model version 2 is greater than those built with version 1, with a mean chain length of 23 for version 2 and 16 for version 1. The longer chain length means that the resulting model has fewer chain breaks and will require fewer choices during sequence alignment.
