Read count and alignment distribution example taken from one sample. The figures were produced using all read counts per category, not just unique reads per category. The other samples in this study follow a similar pattern. a. Read count distribution after trimming adaptors. The smaller peak at 22 base pairs indicates the abundance of miRNA and the larger peak at 33 base pairs indicates the abundance primarily of tRNA. b. The reads alignment distribution by RNA type. The majority of the reads aligned to tRNA instead of miRNA
