Figure 4From: Pan-genome sequence analysis using Panseq: an online tool for the rapid analysis of core and accessory genomic regionsHierarchical clustering of SNPs among six Listeria monocytogenes strains. Hierarchical clustering of the SNPs within the core genome of the Listeria monocytogenes strains F6900, 10403S, Clip81459, EGD-e, HCC23 and 4bF2365. The core genome was generated using the Panseq Core/Accessory Genome Analysis module with fragmentation size of 500 bp and sequence identity cutoff value of 85%. The dendrogram was produced by the statistical package R, using the hclust function with Euclidean distance and average linkage after substituting the ACTG character values with 0,1,2,3 respectively; black = "A", white = "T", red = "C" and green = "G".Back to article page
