Figure 4
The improvement in model quality for cycles of density modification followed by autotracing for the fibronectin test structure starting from sulfur-SAD phases. The colour indicates the deviation of the Cα atoms from their true positions. Each row represents the protein from the N- to the C-terminus. In the first cycle, 41% was traced with Cα atoms within 1.0 Å, 33% within 0.5 Å and 4% incorrectly traced. After three cycles the figures were 94, 87 and 0%, respectively.
