taxidTools is a Python library to handle Taxonomy definitions.

• Load taxonomy defintions for the NCBI's taxdump files
• Prune, filter, and normalize branches
• Save as JSON for later use
• Determine consensus, last common ancestor, or distances
• Retrieve ancestries or list descendants
• Export as Newick trees

With pip:

pip install taxidtools

With conda:

conda install -c conda-forge taxidtools

With docker:

docker pull gregdenay/taxidtools

With the NCBI's taxdump files installed locally:

>>> import taxidTools
>>> tax = taxidTools.read_taxdump('nodes.dmp', 'rankedlineage.dmp', 'merged.dmp')
>>> tax.getName('9606')
'Homo sapiens'
>>> lineage = tax.getAncestry('9606')
>>> lineage.filter()
>>> [node.name for node in lineage]
['Homo sapiens', 'Homo', 'Hominidae', 'Primates', 'Mammalia', 'Chordata', 'Metazoa']
>>> tax.lca(['9606', '10090']).name
'Euarchontoglires'
>>> tax.distance('9606', '10090')
