Using Multiple Sequence Alignment Editors and Formatters: Figure 1.

Abstract

INTRODUCTIONSequence alignment editors enable the user to manually edit a multiple sequence alignment (msa) in order to obtain a more reasonable or expected alignment. Editors allow sequences to be reordered and/or modified using the computer’s cut and paste commands. They are designed to accept various msa formats and to provide the output file in a suitable user-designated format. Sequence formatters provide various output formatting options, such as color and shading schemes to enhance visualization of residue alignments. The formatters can output files in Postscript, EPS, RTF, and other widely recognized formats, while accepting the standard input formats, such as MSF, ALN, and FASTA. This article introduces a number of sequence alignment editors and formatters, and provides links to sites where they can be found.
