phylox.networkproperties.properties.blob_properties

phylox.networkproperties.properties.blob_properties(network)

finds a list of all blobs of the network and their properties. Each blob is a pair (blob_size, blob_level) where blob_size is the number of nodes in the blob and blob_level is the number of reticulations in the blob.

Parameters:

network – a phylogenetic network.

Returns:

a list of pairs (blob_size, blob_level)

Example:

>>> from phylox import DiNetwork
>>> from phylox.networkproperties.properties import blob_properties
>>> network = DiNetwork(
...     edges=[(1,2),(2,3),(2,4),(3,4),(3,5),(4,6),(6,7),(6,8),(7,8),(7,9),(8,10)],
... )
>>> blob_properties(network)
[(3, 1), (3, 1)]

>>> network = DiNetwork(
...     edges=[(0,1),(1,2),(1,3),(2,4),(3,5),(2,5),(3,4),(4,6),(5,7)],
... )
>>> blob_properties(network)
[(5, 2)]
