phylo2owl [input.(tre|nex|xml|...)] [-f format] [-o output.owl]
Command line options
- Default: read a Newick tree from standard input, write an OWL representation of the tree to standard output.
- Input files: Tree files to convert.
- Output (
-o): Where the output ontology should be written. The base name of this file (e.g. 'output' in 'output.owl') is used as the short prefix for nodes in this ontology in the output file.
- Output name (
--name): A short name for the ontology. Defaults to the name of the output file.
- Format (
--format): Currently, 'newick', 'nexus' and 'nexml' are supported.
- Help (
--help): Describes the usage of the program and every command line option.
- Read single tree in Newick format
- Read multiple trees in Newick format?
- Should be easy to modify outputs -- we’re going to spend a lot of time iterating on the best way to represent trees in OWL!
- Phyloreferences will not be represented at this stage: we’ll write
another tool to write phyloreferences in OWL, and then a third tool
to query a phyloreference (in OWL) on a tree (in OWL).
- A separate test suite will test the outputs. Alternatively, we could include a owl2phylo file, and then test to see if we can convert files in one direction and then the other.
- Use library (see below) to load input tree file in a node-based representation.
- Write out a standard header based on https://github.com/hlapp/phyloref/blob/master/Campanulaceae.owl
- For each node in the tree:
- Write out the node using our individual template
- (Bonus!) Write out any other metadata associated with that node in OWL.
- Write out a standard footer.
We use the py.test testing framework. You can
run the tests by running
py.tests tests from this directory.
We currently use DendroPy. Some other libraries we considered include:
