Figure 2: X chromosome data.
From: Accurate whole human genome sequencing using reversible terminator chemistry
a, Distribution of mapped read depth in the X chromosome data set (NA07340), sampled at every 50th position along the chromosome and displayed as a histogram (‘All’). An equivalent analysis of mapped read depth for the unique subset of these positions is also shown (‘Unique only’). The solid line represents a Poisson distribution with the same mean. b, Distribution of X chromosome uniquely mapped reads as a function of G+C content. Note that the x axis is per cent G+C content and is scaled by percentile of unique sequence. The solid line is average mapped depth of unique sequence; the grey region is the central 80% of the data (10th to 90th centiles); the dashed lines are 10th and 90th centiles of a Poisson distribution with the same mean as the data.
