Cross-validation accuracy in the training data using various combinations of feature sets. Random forest ensembles were trained using the feature sets shown in the tables below each bar, and classification accuracy was evaluated by cross-validation. Sufficient SCNA data was available for only six of ten primary sites; thus we analyzed these six sites separately when including SCNAs. a Classification accuracy when excluding SCNAs and distinguishing between ten primary sites. b Classification accuracy when including SCNAs and distinguishing between six primary sites. Accuracy of individual sites are indicated by colored circles. The two combinations of feature sets selected for further analysis are indicated at the top; PM: point mutations only, PM + CN: point mutations and copy number aberrations
