Performance summary of mRRBS. Ninety-six samples were processed using mRRBS and sequenced with eight lanes of Illumina HiSeq 2000 using 12 barcoded adapters per lane. (a) The total number of reads for each sample is shown 84 samples with >5 million total reads were included in the subsequent comparisons. (b) Quartile plots of summary coverage depth from these samples. The minimum and maximum values are bounded by the light blue area in (b-d), while the darker blue area represents the interquartile range. The dark blue line indicates the median. (c,d) MspI in silico digestion of the hg19 genome produced a total of 1,124,739 fragments. (c) The percentage of fragments of each fragment size that were covered by at least one read. (d) The average coverage depth for fragments of each length. Genomic MspI-digested fragments longer than 300 bp were not included in the sequence alignment target, which partly contributes to the sharp drop in coverage at 300 bp in (c,d).
