Differences between TaxMapper, LCA and best hit. Given the green leaves as possible hits, with the best hit circled in green, TaxMapper compares the best hits on a higher taxonomic level (blue circle) and uses the better hit (blue node) if the differences between the hits are large enough, while LCA is a bottom-up method that possibly returns the root of the taxonomy (red node) if the hits are too diverse
