Summary of predicted regions and experimental validation by transient transfection assays and 5′-RACE experiments. Numbers in parentheses indicate the number of validated and tested but unvalidated regions in each category. A region is considered tested if it was tested by either transient transfection assays or 5′-RACE experiments; the validated status is similarly defined. Common4 are regions common to all four methods. Shared are regions predicted by two or three methods. NB, Z, V, and TW indicate regions uniquely predicted by naïve Bayes, Z-score, voting, and tree-weighting methods, respectively. Each class is represented by two pieces of the pie, with the darker colored one indicating novel regions and the lighter colored one indicating known regions. Note that due to the substantially different validation rates of the two experimental approaches and the uneven selection of method-unique regions, there are not sufficient data to directly compare the performances of the methods.
