Figure 5
The standard deviation on τ of the four refinement programs (a) CNS, (b) REFMAC, (c) X-PLOR and (d) SHELXL. Resolution bins and secondary-structure colouring are as in Fig. 4. The global σ, indicated in red and blue, is the same in all four panels and is the same as in Fig. 4. The σ values that resulted from structures refined with the indicated refinement software are shown in pink (sheet), brown (loop) and light blue (helix). We gave all plots the same dynamic range on the x axis for clarity. Points on the vertical axes actually fall outside the range of the x axis. The true values are available from the associated web pages. |
