Additional file 9 of SweepCluster: A SNP clustering tool for detecting gene-specific sweeps in prokaryotes

Additional file 9: Fig. S1 The phylogenetic trees for selection of non-redundant strains. (A) The trees for each of the seven groups of strains. The grouping was based on the submission institutions. The strains selected for downstream analysis in each group are indicated in red square. (B) The final phylogenetic tree for 209 selected non-redundant genomes. (C) The two subpopulations used for identification of SNPs associated with population differentiation are indicated with numbers.
