### den

#### Description

display a hierarchical clustering in a dendrogram

the result is an Encapsulated PostScript image

#### Synopsis

den [-2] [-a] [-b float] [-c] [-C] [-e float] [-f int] [-h] [-H] [-L] [-n int] [-o filename] [-p] [-r float] [-R] [-s float] [-S float] [-t] [-u filename] [-T] cluster-file

den -I|-P|-Q -n int [-a] [-b float] [-e float] [-f int] [-o filename] [-r float] [-R] [-s float] [-S float] [-t] [-T] cluster-file

den -E [-o filename]

#### Options

-2
  PostScript level 2 (default: level 1)
-a
  curved links (default: rectangular)
-b float
  base offset, may be negative (default: minimum of 0.0 and smallest value in cluster file)
-c
  color links (with number of groups from 2 through 19)
-C
  color labels (with number of groups from 2 through 19)
-e float
  exponent (default: 1.0)
-E
  example cluster file
-f int
  fontsize (default: 8)
-h
  use rainbow colours, light and dark, instead of standard colours (no limit to number of groups)
-H
  use rainbow colours, light, instead of standard colours (no limit to number of groups)
-I
  cluster numbers (implies: -L)
-L
  no labels
-n int
  number of groups (default: 1)
-o filename
  output file
-p
  placement of labels in two columns
-P
  patterns (implies: -2 -L, with number of groups from 2 through 19)
-Q
  symbols (implies: -L, with number of groups from 2 through 19)
-r float
  line skip for ruler
-R
  no ruler
-s float
  line skip within groups
-S float
  line skip between groups
-t
  triangular links (default: rectangular)
-T
  font Times-Roman (default: Helvetica)
-u filename
  user-defined colours, see Colour file

#### Purpose

This program can be used to transform a hierarchical clustering, created by the cluster program, into an Encapsulated PostScript image.

#### Example

Since both cluster and den read from standard input and write to standard output, these programs can be joined in a pipe:

        cluster -wm diftable | den > dendrogram.eps
