  • The accuracy of several multiple sequence alignment

    There have been many algorithms and software programs implemented for the inference of multiple sequence alignments of protein and DNA sequences. The true alignment is usually unknown due to the incomplete knowledge of the evolutionary history of the sequences making it difficult to gauge the relative accuracy of the programs. We tested nine of the most often used protein alignment
