Pie charts depicting the frequency of different classes of RNA species present in the sRNA datasets. The pie charts represent an overview of the distribution of small RNAs in the different tissue libraries. For the male brain and female brain, the miRNAs constitute the most abundant sRNA, for the male gut, female gut, male liver and female liver, the tRNAs constitute the most abundant sRNA, and for the eye and heart, the miRNAs and tRNAs equally constitute the most abundant sRNAs. The ovary, testis and embryo had comparatively lesser amount of miRNAs. The ovary and testis had nearly half of their sRNA reads unannotated
