Usage: qiime quality-control evaluate-taxonomy [OPTIONS]
This visualizer compares a pair of observed and expected taxonomic
assignments to calculate precision, recall, and F-measure at each taxonomic
level, up to maximum level specified by the depth parameter. These metrics
are calculated at each semicolon-delimited rank. This action is useful for
comparing the accuracy of taxonomic assignment, e.g., between different
taxonomy classifiers or other bioinformatics methods. Expected taxonomies
should be derived from simulated or mock community sequences that have known
taxonomic affiliations.
Inputs:
--i-expected-taxa ARTIFACT FeatureData[Taxonomy]
Expected taxonomic assignments [required]
--i-observed-taxa ARTIFACT FeatureData[Taxonomy]
Observed taxonomic assignments [required]
--i-feature-table ARTIFACT FeatureTable[RelativeFrequency]
Optional feature table containing relative frequency
of each feature, used to weight accuracy scores by
frequency. Must contain all features found in expected
and/or observed taxa. Features found in the table but
not the expected/observed taxa will be dropped prior to
analysis. [optional]
Parameters:
--p-depth INTEGER Maximum depth of semicolon-delimited taxonomic ranks
to test (e.g., 1 = root, 7 = species for the greengenes
reference sequence database). [required]
--p-palette TEXT Choices('Set1', 'Set2', 'Set3', 'Pastel1', 'Pastel2',
'Paired', 'Accent', 'Dark2', 'tab10', 'tab20', 'tab20b', 'tab20c',
'viridis', 'plasma', 'inferno', 'magma', 'terrain', 'rainbow')
Color palette to utilize for plotting.
[default: 'Set1']
--p-require-exp-ids / --p-no-require-exp-ids
Require that all features found in observed taxa must
be found in expected taxa or raise error.
[default: True]
--p-require-obs-ids / --p-no-require-obs-ids
Require that all features found in expected taxa must
be found in observed taxa or raise error.
[default: True]
--p-sample-id TEXT Optional sample ID to use for extracting frequency
data from feature table, and for labeling accuracy
results. If no sample-id is provided, feature
frequencies are derived from the sum of all samples
present in the feature table. [optional]
Outputs:
--o-visualization VISUALIZATION
[required]
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).
--example-data PATH Write example data and exit.
--citations Show citations and exit.
--help Show this message and exit.
