Circular chromosome map of Salinicoccus halodurans H3B36. From inner to outer: 1, GC skew (GC Skew is calculated using a sliding window, as (G – C) / (G + C), with the value plotted as the deviation from the average GC skew of the entire sequence); 2, GC content (plotted using a sliding window, as the deviation from the average GC content of the entire sequence); 3, tRNA/rRNA; 4 and 5, CDS (colored according to COG function categories, where 4 is the reverse strand and 5 is the forward strand); 6 and 7, m4C and m6A sites in CDS/rRNA/tRNA (6 is the reverse strand and 7 is the forward strand); and 8, m4C and m6A sites in intergene regions
