Figure 6.

Selected features in each of the two data sets (as specified) for the six-class classifier: antisense expression (antisense), 5′ and 3′ smRNA positional entropy (pos_entropy5p and pos_entropy3p), nucleotide preference (nuc_A, nucC, nuc_G and nuc_T), MFE value and the smRNA length features from 14 to 30 nt (L14–L30). The sign of the value indicates whether the feature was larger (positive) or smaller (negative) within that class, on average, than the other classes (by difference of means).
