Circos plot showing SNP-distribution in the genome of A. baumannii PKAB07 and its correlation with accessory genome and the GC-skew (From inside out) Track-1 (green) - regions that are absent in at least one of the genomes (the accessory genome). Track-2 (red) – The chromosome of A. baumannii PKAB07. Track-3 (purple/orange) – Histogram showing GC-skew. Track-4 (red) – Scatter plot of SNP count/kb. Note the scattering of the plot outward at genomic regions where either a steep deviation from the GC-skew occurs or a syntenic link appears, or both (particularly, regions around 0.1 –0.3 Mb, 0.7–1 Mb, 1.2 Mb, 2–2.3 Mb; the outer numbers showing genomic coordinates in mb)
