NAME
       AnalyseDists - Analyse a	distance matrix

SYNOPSIS
       AnalyseDists [-X[swn]]

DESCRIPTION
       AnalyseDists  reads  a distance matrix (given as	lower triangle matrix)
       from stdin and writes a split decomposition and a cluster  analysis  of
       this  distance  matrix  to stdout.  The line before the distance	matrix
       must be of the form
       > Y x [comments]
       where 'x' gives the number of taxa, 'Y' is a single character that  in-
       dicates	the  type  of  distance	and 'comment' is an arbitrary comment.
       This matches the	output format of, e.g.,	RNAdistance.  The  input  data
       file  may contain arbitrary lines before	and after the distance matrix.
       All lines beginning with	'> ' that are not of the above form are	 writ-
       ten to stdout. The program continues reading until it encounters	an EOF
       condition or the	terminator character '@'.
       A  list	of  taxa  names	can be specified in the	input stream. The list
       must begin with a line of the form
       * [fname]
       if fname	is present, it will be used  to	 name  the  postscript	output
       files.  The entries have	the form 'x : Taxon', where x is the number of
       taxon,  i.e.,  the corresponding	row and	column of the distance matrix.
       The taxa	list need not be complete. It must end however with a line be-
       ginning with '*'	or any of the separator	characters. The	taxa  list  is
       printed on top of the output.

OPTIONS
       -X[swn]
	      specifies	the analysis methods to	be used.

       [s]    Split decomposition.

       [w]    Cluster  analysis	 using	Ward's method. A PostScript file named
	      '[fname_]wards.ps' is created containing a drawing of the	tree.

       [n]    Cluster analysis using Saitou's  neighbour  joining  method.   A
	      PostScript  file	named  '[fname_]nj.ps' is created containing a
	      drawing of the tree.

REFERENCES
       The method of split decomposition was  proposed	by  H.J.  Bandelt  and
       A.W.M. Dress (Adv Math, 92:1992,47).
       The  variance method for	cluster	analysis is due	to H.J.	Ward.  (J Amer
       Stat Ass, 58:1963,236).
       The neighbour joining method was	published by Saitou and	Nei (Mol  Biol
       Evol, 4:1987,406).
       This program is part of the Vienna RNA Package.

WARNING
       This a beta test	version.
