What does MSWAT do? MSWAT conducts multiple sequence alignment for phylogeny and molecular evolutionary comparisons. It was initially designed to align shared genes from completely sequenced chloroplast genomes (see Cai et al. BMC Evol Biol. 2006; 6: 77 for an example). MSWAT has been used to generate an alignment for 81 chloroplast genes for 64 taxa (see Jansen, R. K et al. PNAS 104 (49), 19369-19374). It can be used to expand this data matrix by adding chloroplast genomes. It can also be used to align any sequences from other genomes.

How does MSWAT work? MSWAT uses fasta-formatted nucleotide sequence files as input. All protein-coding nucleotide sequences in the input files are translated into amino acid sequences, which are aligned using MUSCLE and/or ClustalW, followed by manual adjustments, and then nucleotide sequences of these genes are aligned by constraining them to the aligned amino acid sequences. Multiple files of different formats with character sets for phylogenetic analyses are generated after nucleotide sequence alignment is completed.
