Figure 3.

A statistical analysis of current computational approaches for promoter prediction. (A) The numbers of annual publications for prokaryotic and eukaryotic promoter prediction since 2000. Different colors represent different types of predictors, including promoter prediction tools for prokaryote, eukaryote and both. (B) Length distribution of prokaryotic and eukaryotic promoter sequences from a variety of training datasets. (C) Comparison of frequency of computational approaches applied promoter prediction for prokaryote and eukaryote. (D) Pie charts demonstrating the types and availability of prokaryotic and eukaryotic promoter prediction tools.
