  1. Libraries were prepared from 100 ng of NA12878. Data was generated on a HiSeq X (2 × 151 bp) and data analysis performed using the BaseSpace Sequence Whole Genome Sequencing Application. a Callability describes the percentage of base calls in the data set that pass the quality metrics required for making a genotype call; base quality, alignment quality, and minimum coverage levels are considered. SNV Single-nucleotide variant, Indel Insertion/deletion
