MAFFT is a program for the multiple alignment of nucleic acid or protein sequences, and is available from the Web Service→Alignment→MAFFT Multiple Sequence Alignment entry in the web services menu.
MAFFT utilizes algorithms for spectral correlation to identify homologous regions in a fast-fourier transform representation of each sequence. The Jalview web service runs MAFFT using the '--auto' option which picks optimal parameters for the set of sequences to be aligned.
