merge-taxa: Compare taxonomies and select the longest, highest scoring, or find the least common ancestor.¶

Docstring:

Usage: qiime rescript merge-taxa [OPTIONS]

  Compare taxonomy annotations and choose the best one. Can select the longest
  taxonomy annotation, the highest scoring, or the least common ancestor.
  Note: when a tie occurs, the last taxonomy added takes precedent.

Inputs:
  --i-data ARTIFACTS... List[FeatureData[Taxonomy]]
                         Two or more feature taxonomies to be merged.
                                                                    [required]
Parameters:
  --p-mode TEXT Choices('len', 'lca', 'score', 'super', 'majority')
                         How to merge feature taxonomies: "len" will select
                         the taxonomy with the most elements (e.g., species
                         level will beat genus level); "lca" will find the
                         least common ancestor and report this consensus
                         taxonomy; "score" will select the taxonomy with the
                         highest score (e.g., confidence or consensus score).
                         Note that "score" assumes that this score is always
                         contained as the second column in a feature taxonomy
                         dataframe. "majority" finds the LCA consensus while
                         giving preference to majority labels. "super" finds
                         the LCA consensus while giving preference to majority
                         labels and collapsing substrings into superstrings.
                         For example, when a more specific taxonomy does not
                         contradict a less specific taxonomy, the more
                         specific is chosen. That is, "g__Faecalibacterium;
                         s__prausnitzii", will be preferred over
                         "g__Faecalibacterium; s__"           [default: 'len']
  --p-rank-handle-regex TEXT
                         Regular expression indicating which taxonomic rank a
                         label belongs to; this handle is stripped from the
                         label prior to operating on the taxonomy. The net
                         effect is that ambiguous or empty levels can be
                         removed prior to comparison, enabling selection of
                         taxonomies with more complete taxonomic information.
                         For example, "^[dkpcofgs]__" will recognize
                         greengenes or silva rank handles. Note that
                         rank_handles are removed but not replaced; use the
                         new_rank_handle parameter to replace the rank
                         handles.                   [default: '^[dkpcofgs]__']
  --p-new-rank-handles VALUES... List[Str % Choices('disable')] | List[Str
    % Choices('domain', 'superkingdom', 'kingdom', 'subkingdom',
    'superphylum', 'phylum', 'subphylum', 'infraphylum', 'superclass',
    'class', 'subclass', 'infraclass', 'cohort', 'superorder', 'order',
    'suborder', 'infraorder', 'parvorder', 'superfamily', 'family',
    'subfamily', 'tribe', 'subtribe', 'genus', 'subgenus', 'species group',
    'species subgroup', 'species', 'subspecies', 'forma')]
                         Specifies the set of rank handles to prepend to
                         taxonomic labels at each rank. Note that merged
                         taxonomies will only contain as many levels as there
                         are handles if this parameter is used. This will trim
                         all taxonomies to the given levels, even if longer
                         annotations exist. Note that this parameter will
                         prepend rank handles whether or not they already
                         exist in the taxonomy, so should ALWAYS be used in
                         conjunction with `rank-handle-regex` if rank handles
                         exist in any of the inputs. Use 'disable' to prevent
                         prepending 'new-rank-handles'
[default: ['domain', 'phylum', 'class', 'order', 'family', 'genus', 'species']]
  --p-unclassified-label TEXT
                         Specifies what label should be used for taxonomies
                         that could not be resolved (when LCA modes are used).
                                                       [default: 'Unassigned']
