MView, release 1.37

    http://mathbio.nimr.mrc.ac.uk/nbrown/mview/     **Note NEW URL**

MView is a free tool for converting the results of a sequence database
search into the form of a multiple alignment of hits stacked against the
query. For completeness, existing multiple alignments can be post-processed
in the same way. A typical application is the generation of a colorized Web
page from a BLAST or FASTA search allowing quick assessment of the hits in
terms of sequence conservation patterns alongside the scoring information.


  Changes in this release include:

   o Extension to the full BLAST suite of programs, notably tblastn by
     popular demand.
   o Column names added to numeric fields (score, expect, etc) for search
     programs in BLAST/FASTA suites.
   o Limited control from command line allowing a subrange of alignment
     columns to be extracted and displayed.
   o Semi-automatic input format detection based on filename or extension and
     specific program/version of BLAST or FASTA suite determined
  Bug fixes:

   o Ordering of HSPs in reverse complemented query strands was wrong for
     blastn (series 1.4).
   o More efficient memory usage.


MView allows filtering of the input by score, e-value thresholds, psi-blast
search cycle, etc., provides a choice of coloring schemes and palettes for
protein or nucleotide sequences, and can generate consensus patterns.

Currently recognised input formats include (*=new):

  NCBI BLAST (2.0 series)
     blastp, blastn, (*)blastx, (*)tblastn, (*)tblastx, psi-blast
  NCBI BLAST (1.4 series)
     blastp, blastn, (*)blastx, (*)tblastn, (*)tblastx
  WashU BLAST2 (2.0)
     blastp, blastn, (*)blastx, (*)tblastn, (*)tblastx
  FASTA (3.0 series)
     fasta3, tfastx3
  FASTA (2.0 series)
     fasta, tfastx
  and the following flatfile formats:
     Pearson, PIR, MSF, CLUSTAL

Alternative output formats are also supported: plain text, Pearson, PIR,
and MSF, for export to other programs. See the Web page for the most recent

This software requires Perl (version 5) and runs on UNIX systems.
