Hexamer frequencies. (a) The logarithm (base 2) of all (4096) observed hexamer frequencies computed using positions 1–6 of the aligned reads for an experiment in H. sapiens (8) versus an experiment in S. cerevisiae (9). The two distributions have a correlation of . (b) As in (a), but the hexamers correspond to positions 25–30 of the aligned reads, with a correlation of
.
