Usage

The following examples requires the python-newick package.

>>> from pylocluster import *
>>> from newick import loads
>>> matrix = squareform([0.5,0.67,0.8,0.2,0.4,0.7,0.6,0.8,0.8,0.3])
>>> nwk = linkage(matrix, taxa=['G', 'S', 'I', 'E', 'D'], method='upgma')
>>> print(loads(nwk).ascii_art())
