Additional file 2: Figures S1 to S6: of MicroRNA categorization using sequence motifs and k-mers

Figure S1 shows the rank distribution for k-mers and motif features. Figure S2 displays how feature selection impacts accuracy. Figures S3 and S4 provide additional accuracy distributions for various clades versus hominidae and Figure S5 provides similar information for Cercopitheciadae and Hominidae versus human. Figure S6 supports the choice of selected number of features. (DOCX 653 kb)
