Read counts and state classifications. Read counts and state classifications for a 57 kb region of the H37Rv genome is shown. Essential regions are shown in green, growth-defect regions in yellow, non-essential regions in red, and growth-advantage regions in blue. Read counts are truncated at 2,000 (with a max of ∼3,000 in this region), and the mean read count in the library is represented by a gray horizontal line.
