This script takes two FASTA files of predicted gene sequences that have been converted to amino acids and calculates the POCP value (Qin et al. 2014; Journal of Bacteriology). The script also takes the number of CPUs to be used for BLASTing as a third parameter. The '_HH' is included at the end of all intermediate files to guarantee that the file names are unique, ensuring that existing files do not get overwritten.
