Raw and mapped sequence data.

aNumber of 2×100-nt read-pairs resulting from HiSeq 2000 sequencing.bRead-pairs containing the sequencing adapter. The left and right reads overlap due to sequencing of DNA fragments cReads without the adapter sequence. These resulted from sequencing of DNA fragments >200-nt. The left and right mate did not overlap and these were mapped as pairs.dThe average sequence length after merging left and right reads.eThe combined number of nucleotides after merging of left and right reads but before mapping.
