Abstract excerpt
Genome sequence contamination has a variety of causes and can originate from within or between species. Previous research focused on contamination between distantly related species or on prokaryotes. Here, we test for intraspecies contamination by mapping short read genome data to a reference and visualizing the frequency of reads with single nucleotide differences from the reference. Out of 1,298 publicly...
