DGB, Dsampleand Dchimare the Hamming distances to the given GenBank entry, the nearest sample genotype, and the optimal chimera for each putative contaminant denoised sequence. No entries are given for the Artificial data set because no likely contaminants were found in the denoised sequences of either algorithm. The last two columns show which contaminants were present in the denoised sequences of each algorithm (“Y” if found and “N” if not found).
