⊥ Fraction of reference that is covered at least once ⊄ Estimated heterozygosity (average over multiplexes). Sample contamination can increase this estimate. Filters: base quality >= 39, mapping quality >= 30, pairs properly mapped, no indels, maximum 2 high-quality (Q30) variants in read, insert size > read length. * Mean coverage is computed over regions that are covered at least once ℵ Proportion of reads in regions with coverage in top 0.1 percentile

∋ The Fraction N/Low Q plots, and dotted lines on the GC histogram plots, refer to all reads that have
passed chastity filters. If a reference genome was available, all others refer to mapped reads, otherwise
they too refer to chastity-filtered reads. The dotted lines in the fraction N/lowQ plot correspond to the
fraction of bases with quality score 4 or less. ∇ "Predicted variants" (dashed line) is the expected error frequency expressed as a Phred score,
and may be compared with the "Variants by cycle" graph (solid line). "Mean Q" (solid) is the numerical
mean Q score and is a measure of the average information content per read. These graphs use mapped reads only;
the dashed line in the Mean Q plot uses all (PF) reads. All four graphs are calculated on called bases with
Q Phred score above 4 only. ℘ Mapped coverage by G+C. The coverage was averaged over those genomic regions that were covered at least once.
Regions with coverage in the top 0.1 percentile were excluded; the dotted line shows results for all reads.
The G+C fraction was computed from read bases, excluding Ns and bases with quality below 4. ∅ Genomic coverage by G+C. The G+C fraction was computed from the reference genome, over the approximate fragment
Regions with coverage in the top 0.1 percentile were excluded.
The G+C histogram is shown as a dotted line (arbitrary Y scale). ∞ The insert size distribution is summarized by the median and median absolute deviation.
