PomBase-Chobo

Prototype code from PomBase for reading OBO files into a Chado database using PostgreSQL COPY.

https://github.com/pombase/chobo

Build status

Features

  • Fast

  • Few dependencies

  • Single command for loading (chobo_load)

Current problems

  • Some OBO files aren't supported because not all edge cases are handled

  • Uses a lot of memory (500MB to read and store GO)

  • Currently ignores stanza tags that PomBase doesn't use (eg. "xref:")

  • The destination Chado database must contain:

    • an is_a relation

    • a CV named "synonym_type" containing all synonym types from the input OBO files

    • a CV named "cv_property_type" containing a term named "cv_version"

    • a CV named "cvterm_property_type" containing terms named "replaced_by" and "consider"

    An example Chado DB containing these is here: https://github.com/pombase/pombase-legacy/blob/master/pombase-chado-base.dump?raw=true

  • Ontologies can't be re-loaded
