The distribution of PriMir scores of the training set and the potential pre-miRNA candidates. Red columns: the 220 known pre-miRNAs in the training set; blue columns: the 23 known pre-miRNAs in ml-ncRNAs; green columns: the predicted 4463 conserved hairpins. The red arrow indicates the cutoff value "7" PirMir used to predict candidate pre-miRNAs. Hundred and sixty-one (73%) of the 220 known pre-miRNAs fall above this cutoff. Of the 23 known pre-miRNAs located in ml-ncRNAs, 18 (78%) have scores higher than 7.
