Fig. 4

The correlation between sample age and various measures of sequencing quality, including saturation, total number of mapped reads, mean coverage, total number of reads on target, enrichment, and total number of baits with 1x coverage, when reads were aligned to the targets. In (a), each bar in the plot represents the strength and direction of correlation, and the R-value is displayed in/on the bars. In (b), the raw data points are plotted for each pair-wise comparison, along with the linear regression trend line. See Table 2 for the detailed statistics. Note that the total number of baits at 5x, 10x, 20x, and 30x coverage are excluded from these plots as they were highly correlated with the total number of baits at 1x coverage
