This is a script to import the MPO, originally in OBO format to tabular format that can be easily handled with R.
The MPO is under development as a community effort to provide standard terms for annotating mammalian phenotype data. An ontology is a standardized, controlled vocabulary that contains phenotypic information (in this particular case phenotypic abnormalities in mouse mutants).
More information can be found here: http://obofoundry.org/ontology/mp.html
The ontology can be visualized here through an ontology browser: https://www.informatics.jax.org/vocab/mp_ontology/ (click question mark at the top left for more info)
