display a hierarchical clustering in a dendrogram

the result is an Encapsulated PostScript image

den -E [-o filename]

-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

-O

reorder colours

-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

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

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