Abstract: | This paper describes a multiple alignment method using a workstationand supercomputer. The method is based on the alignment of aset of aligned sequences with the new sequence, and uses a recursiveprocedure of such alignment. The alignment is executed in areasonable computation time on diverse levels from a workstationto a supercomputer, from the viewpoint of alignment resultsand computational speed by parallel processing. The applicationof the algorithm is illustrated by several examples of multiplealignment of 12 amino acid and DNA sequences of HIV (human immunodeficiencyvirus) env genes. Colour graphic programs on a workstation andparallel processing on a supercomputer are discussed.
