title: BGISEQ-500 paired end sequencing
design: NA12878 is a reference human DNA sample, which has qpcr database. So the sample can be used to estimate the accuracy of high-throughput sequencing platform for DNA resequencing
library_construction_protocol: the NA12878 genomic DNA was fragmented by ultrasonic on Covaris E220 to 50 bp~800 bp DNA fragments . The fragmented DNA was further selected to 100 bp~300 bp by AMPure XP
