Short for “Genbank Mutation Locator”. A simple Python3 package that if you pass it a mutation it will give you the location in the specified genbank file.

> gemucator-run.py --mutation rpoB_S450L
rpoB_S450L:
761153 t
761154 c
761155 g

(H37rV.gbk for M. tuberculosis is loaded by default). Or you can go the other way

> gemucator-run.py --location 761153
rpoB_S450

It has no unit testing, but checks that the mutation is consistent with the genbank file which means you can check if your genetic catalogue is correct.

> gemucator-run.py --mutation rpoB_K450L
