EasyBack vs TIP and BACKTRANSEQ. Performance of EasyBack compared with TIP and BACK-TRANSEQ based on percentages of amino acids correctly decoded. Easyback and TIP were tested using BLAST All-Species training sets. BACKTRANSEQ used Species-Specific training sets. For all systems each training set comprised 100 sequences. Classical Viterbi algorithm (EasyBack-Vit) and a posterior decoding technique based on a forward-backword algorithm (EasyBack-FB) were used to make predition.
