Size class and complexity distributions of sequencing reads.

<p>Size distribution and complexity are shown for (A) all reads, (B) reads mapping to the Human genome, (C) reads mapping to the SINV genome. Subplots A1, B1 and C1 show the read number for 21–24 mers at 0, 4 and 6hpi. Subplots A2, B2 and C2 show the complexity for each size class from 17–27 mers, where the complexity is the ratio of non-redundant reads to redundant reads.
