Heat Map indicating probability distribution of spoligotype spacers and MIRU loci by lineage. The probability of a spacer being present at each of the 43 loci of the spoligotype is shown for each lineage. Each MIRU locus is modelled as a multinomial distribution with possible values 0, 1…8, and ≥ 9 (9+). In the MIRU heat map for each lineage, the X axis represents the MIRU loci, Y axis the number of tandem repeats, and each square represents the probability of occurrence of the number of repeats at the specified locus. The range of probability values from 0 to 1 are depicted by colors ranging from black to white.
