Figure 5

Quality of 75 879 sequences from The 1000 Genomes Project which match one or more Mycoplasma genomes but do not match the reference human genome. Horizontal and vertical noise added to spread data. Most sequences which fail to match GRCh37.p5 but do match one or more species of Mycoplasma are of low quality. Nevertheless an important fraction are of high quality and match Msycoplasma with no or few mismatches. As with Figure 3, data are split in four by type of sample preparation and sequencing machine.
