BW25113 - wild type

This is the wild type strain used for barcoding purposes in E. coli

The script used to find the barcoding site (essential_pair_finder.py) is attached. The script uses as input the .gff3 annotation file (BW25113.gff3) and the essential genes file (keio_genes_synonimschanged.txt). 

It prints as output the closest pair of essential genes.
