This program performs hierarchical clustering on a
difference matrix file and produces a
hierarchical cluster definition file, unless
option -b or -c was used.
This clustering file can then be processed further with
den to create an image of a dendrogram, or
with
clgroup to produce a partitioning of the
data. With option -b or -c, the result can be used to create a differentiated
cluster map with
mapdiff.
The program will abort if a file _CANCEL_.L04 exists in the current directory,
or if it is created while the program is running. This is useful for stopping
long running calculations from a GUI, such as
pyL04.
The clustering algorithms implemented in this program are described in:
