  1. The dataset contains five RNA families: tRNAs, miRNAs, 5S rRNAs, H/ACA snoRNAs, and C/D snoRNAs. ncRNA type: name of the target ncRNA family. ROC: ROC score, equal to the area under the ROC curve. SP: specificity of the discrimination of the target ncRNA family. SN: sensitivity of the discrimination of the target ncRNA family. Time: averaged time for each kernel computation on a 2.0 GHz AMD Opteron processor.
