skbio.core.tree.TreeNode.compare_subsets¶

TreeNode.compare_subsets(other, exclude_absent_taxa=False)[source]¶

Returns fraction of overlapping subsets where self and other differ.

Names present in only one of the two trees will count as mismatches, if you don’t want this behavior, strip out the non-matching tips first.

Parameters:	other : TreeNode The tree to compare exclude_absent_taxa : bool Strip out names that don’t occur in both trees
Returns:	float The fraction of overlapping subsets that differ between the trees

>>> tree1 = TreeNode.from_newick("((a,b),(c,d));")
