 ## Content of this repo
 A single python script (no installation needed) parses all the annotation files and produce another set of annotation files with the suffix `.uniform.txt`.
 The mapping of annotations is available in the `mappings.txt` file in the form `A|B|C` (see [https://zzz.bwh.harvard.edu/luna/ref/annotations/#remap] for details), meaning that every instance of `B` or `C` will be mapped as `A`. If a mapping does not exist, the original value is returned with a prefix `misc:`.
