Figure 3From: Sequence space coverage, entropy of genomes and the potential to detect non-human DNA in human samplesThe percentage of n -mers that appeared exactly once (unique hits), out of all the n -mers detected in each genome. Slightly less than 50% of 16-mers detected in humans are unique. Whereas, for E. coli, a little more than 50% of 12-mers were unique.Back to article page
