Filtering criteria are applied by affiliation. So for blast, filters are not only applied on the blast consensus taxonomy but on each blast hit (cf multihit.tsv file). For each ASV, none, part or all blast affiliations may be removed, resulting in unchanged / updated or deleted blast consensus taxonomy. The detailed number of lost affiliations (not only the consensus) by rank are summarised. It may also precise if blast consensus multi-affiliation are lost.
