derive a partitioning from a hierarchical clustering

clgroup -n int [-i] [-o filename] cluster-file

-i

Indexed output

-n int

Number of groups

-o filename

Output file

This program can be used to transform a hierarchical clustering, created by the cluster program, into a partitioning of the original data.

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

    cluster -wm diftable | clgroup -n 4 > partitioning.txt
