Fgenesv+ predictions are based on Softberry's gene-finding software for viral genomes.
The Fgenesv gene prediction algorithm is based on pattern recognition of different types of signals and Markov chain models of coding regions. The optimal combination of these features is found by dynamic programming; a set of gene models is constructed along the given sequence. Fgenesv+ is the Softberry automatic annotation pipeline that uses the Fgenesv gene predictor and annotations of predicted proteins, comparing them with protein databases. For more information, see Softberry's Fgenesv web page.
The Fgenesv+ gene predictions were produced by Softberry Inc. Thanks to Victor Solovyev for providing these data.
