Psa2msa reformats a psa-formatted profile-sequence alignment file into a Pearson or Fasta-formatted multiple sequence alignment file. *psa_file* contains alignments of several sequence segments to the same profile in psa format. Such a file is typically generated by the programs pfsearch or pfscan using option -x. The output can be converted into other formats (e.g. MSF) with the aid of the public domain program readseq (available from ftp: or or ftp.bio.indiana.edu or molbio or readseq) or used directly with pfmake or pfw.
