The accuracy of the software has been tested on a set of 100 vertebrate
promoters. The positions scoring 0.5-0.8 (Marginal predictions) contain
about 65% true transcription start sites within 100 base pairs upstream.
The positions scoring 0.8-1.0 (Medium likely predictions) are about 80%
true. Finally, the positions scoring above 1.0 (Highly likely predictions)
are about 95% true. On average, the software picks up about 80% of all PolII
promoters. These numbers are rough estimates based on a limited test set.
