Extended Data Figure 2. Data and model quality.
Plots of CC*, CCfree and CCwork against resolution, for the tetragonal crystal data set and model. The CC* statistic assesses the signal present in the data, while CCfree and CCwork provide an estimate of the agreement between data and model. A CC* value of 0.87 for the highest resolution shell indicates that these data contain useful information up to 3.9 Å. CCfree and CCwork are lower than CC*, showing that the model does not overfit the data.
