From: Comparative genomics of Drosophila and human core promoters
The localization of all 65,536 8-mers in Drosophila and human promoters. The clustering factors (CF or CF+) calculated for 20 bp bins plotted at the position of the most populated bin for all 65,536 8-mers. (a) CF for 10,914 Drosophila promoters; (b) CF for 15,011 human (UCSC) promoters; (c) CF for 12,926 human (DBTSS) promoters; (d) CF+ for 10,914 Drosophila promoters; (e) CF+ for 15,011 human (UCSC) promoters; (f) CF+ for 12,926 human (DBTSS) promoters.
