Features Analysis Benchmark Protocol Capture


High-resolution crystal structures are assumed to be thermodynamically stable, which means that each structure should occupy a minimum of a high quality energy function. In particular, in aggregate, Rosetta should reproduce local structure features observed in the high quality crystal structures. Therefore if we relax native crystal structures and observe systematic displacement of local geometric features (specific types of bonds are lost, polar contacts become too close, etc.) this indicates that when new structures are predicted, they will likely not be stable in the lab.

In our 2015 H-bond paper, we observed that the interaction between related terms in the energy function create areas of double counting for certain types of interactions or contexts that may be maybe difficult to observe in full structure benchmarks. By plotting and looking closely at distributions of local features, it is possible to gain a deeper understanding of the full energy that arises from the complex interaction between the range of active terms and the implicit kinematic constraints.
