Average percentage from 11 outbreaks. The S. enterica outbreak 1203NYJAP-1 was removed as an outlier because all pipelines except wgMLST produced errors with grouping outbreak vs. non-outbreak isolates. Therefore this dataset was removed from the Sn and Sp calculations as an outlier.
Geometric mean.
Number of SNPs per Lyve-SET SNP, averaged across 12 outbreaks. For wgMLST, this is the number of alleles per Lyve-SET SNP.
The average for 12 outbreaks. First value is for all data points; second value is for distances between only outbreak-associated genomes.
The average for 12 outbreaks. Percentage of the reference genome included for analysis. For wgMLST, the average percentage was calculated by obtaining each GenBank-formatted file with annotated wgMLST loci and calculating the breadth of coverage for all loci.
