SeaView is a graphical multiple sequence alignment editor developped by
Manolo Gouy. SeaView is able to read and write various alignment
formats (NEXUS, MSF, CLUSTAL, FASTA, PHYLIP, MASE). It allows to
manually edit the alignment, and also to run DOT-PLOT or CLUSTALW
programs to locally improve the alignment.
