Scoring with longer fragment lengths. (a) With grid size of 12° and resolution set of 1.8 Å, models T0281TS100_1 (dashed line), T028TS109_1 (dot-dash line), and target 1whz (solid line) were scored for k = 1–10. Best-fit logarithmic curves [m · ln(x) + b] for T0281TS100_1 (m = −0.86) and the target nearly match (m = −0.81). From k = 1 the curve for T028TS109_1 (m = −1.26) descends faster. (b) Forty models from several CASP groups are scored and compared with the target, 1whz (blue line). Most of the models scored poorly for k ≥ 2. Several models scored as well as or better than the target because they were constructed with commonly observed structural fragments.
