Figure 2.

Distributions of conservation scores for actual (red) and randomized (black) data obtained when applying FastCompare to S. cerevisiae and S. bayanus. Both distributions were constructed using bin sizes of 5. The top portion of the figure is not shown for the purpose of presentation. The distributions show that high conservation scores are unlikely to be obtained from randomized data. Also, a large number of 7-mers on the tail of the distribution correspond to experimentally verified transcription-factor-binding sites in yeast.
