Usage: qiime quality-control evaluate-seqs [OPTIONS]

  This action aligns a set of query (e.g., observed) sequences against a set
  of reference (e.g., expected) sequences to evaluate the quality of
  alignment. The intended use is to align observed sequences against
  expected sequences (e.g., from a mock community) to determine the
  frequency of mismatches between observed sequences and the most similar
  expected sequences, e.g., as a measure of sequencing/method error.
  However, any sequences may be provided as input to generate a report on
  pairwise alignment quality against a set of reference sequences.

Inputs:
  --i-query-sequences ARTIFACT FeatureData[Sequence]
                       Sequences to test for exclusion              [required]
  --i-reference-sequences ARTIFACT FeatureData[Sequence]
                       Reference sequences to align against feature sequences
                                                                    [required]
Parameters:
  --p-show-alignments / --p-no-show-alignments
                       Option to plot pairwise alignments of query sequences
                       and their top hits.                    [default: False]
Outputs:
  --o-visualization VISUALIZATION

Miscellaneous:
  --output-dir PATH    Output unspecified results to a directory
  --verbose / --quiet  Display verbose output to stdout and/or stderr during
                       execution of this action. Or silence output if
                       execution is successful (silence is golden).

Compare query (observed) vs. reference (expected) sequences.

This action aligns a set of query (e.g., observed) sequences against a set
of reference (e.g., expected) sequences to evaluate the quality of
alignment. The intended use is to align observed sequences against expected
sequences (e.g., from a mock community) to determine the frequency of
mismatches between observed sequences and the most similar expected
sequences, e.g., as a measure of sequencing/method error. However, any
sequences may be provided as input to generate a report on pairwise
alignment quality against a set of reference sequences.

Parameters
----------
query_sequences : FeatureData[Sequence]
    Sequences to test for exclusion
reference_sequences : FeatureData[Sequence]
    Reference sequences to align against feature sequences
show_alignments : Bool, optional
    Option to plot pairwise alignments of query sequences and their top
    hits.

Returns
-------
visualization : Visualization
