Figure 4From: Evaluation of genomic high-throughput sequencing data generated on Illumina HiSeq and Genome Analyzer systems Observed error rates of 2 Ă— 95-nucleotide HiSeq reads by cycle (averaged across all flow cell tiles). Read 1 (left) and read 2 (right) were analyzed separately for PhiX-95nt data (a) and Bv-95nt data (b). PhiX and sugar beet DNA was sequenced in the same lane, and reads were mapped against the PhiX or ZR reference sequences, respectively.Back to article page
