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  dis-
     tance 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 indi-
     cates 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 be-
     ginning with '> ' that are not of the above form are written to stdout. The
     program continues reading until it encounters an EOF condition or the  ter-
     minator 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 beginning 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  Post-
	    Script 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.
