environ.dendrogram() -- clustering

cluster_cut = <float:1>	1.0	definition of a cluster
matrix_file = <str:1>	'family.mat'	the filename of the pairwise distance matrix

Description:

This command calculates a clustering tree from the input matrix of pairwise distances. This matrix must be in the PHYLIP format and can be produced by the alignment.id_table(), alignment.compare_sequences(), or alignment.compare_structures() commands. The weighted pair-group average clustering method is used.

The tree is written to the log file.

This command is useful for deciding about which known 3D structures are to be used as templates for comparative modeling.

Example: See alignment.id_table() command.
