KEGG-Orthology-parser

When working with genome annotations, you'll likely encounter a long list of KO numbers. In such cases, you might want to include the entire KEGG hierarchy in your annotations for various downstream analyses. Your first thought might be, "If I had a table with the complete hierarchical KEGG orthology, I could simply merge my annotations with it." However, reality and imagination do not always meet face to face. You will find it's not that straightforward to compile hierarchical information formats into simple and readable tables. This script helps parse one of the available KEGG formats, converting the entire orthology into a simple tabular form, preserving the hierachical information in a readable form.
