Correlation of 3D-Jury score in the [30–100) range with the number of correctly predicted C _α atoms. $N_{C_{\alpha }\le 3.5\AA }$ – the number of C _α atoms predicted within 3.5 Å from their respective locations in the crystal structure; Jscore – 3J_1,Ascore; solid green line – prediction of linear model LM₂; blue longdash lines: confidence interval at 95% confidence level; blue dashed lines: prediction interval at 90% confidence level; blue dotdash lines: prediction interval at 95% confidence level; blue dotted lines: prediction interval at 99% confidence level; x – slope; the colour bar is key to the approximate density of models A linear model (LM₂) was fitted to the 3D-Jury score vs. $N_{C_{\alpha }\le 3.5\AA }$ of 6,710 models. The residual standard error is 13.37. The 95% confidence interval as well as prediction intervals for 90%, 95% and 99% confidence levels are indicated on the figure. The vertical and horizontal histograms show the distributions of $N_{C_{\alpha }\le 3.5\AA }$ and 3D-Jury scores respectively. The 30 to 100 3D-Jury score range was chosen to represent difficult targets.
