Table 2. Using BamUtil, basic sequencing statistics of MBD cohort I and II are computed.

Statistic	MBD cohort I—enriched samples			MBD cohort II—enriched samples			MBD cohort II—input samples

Total read number: the total number of reads in the two paired FASTQ files of a sample; duplicate reads as a percentage of the total read number; properly paired reads as a percentage of the total read number.

duplicate reads (%)	0.70–72.00	6.46	3.39	2.55–79.69	31.04	19.89	2.24–10.47	4.17	3.68
properly paired reads (%)	48.29–94.51	85.64	89.29	86.86–97.57	95.33	95.72	94.78–97.55	96.50	96.59
