Usage: qiime composition ancom [OPTIONS]
Apply Analysis of Composition of Microbiomes (ANCOM) to identify features
that are differentially abundant across groups.
Inputs:
--i-table ARTIFACT FeatureTable[Composition]
The feature table to be used for ANCOM computation.
[required]
Parameters:
--m-metadata-file METADATA
--m-metadata-column COLUMN MetadataColumn[Categorical]
The categorical sample metadata column to test for
differential abundance across. [required]
--p-transform-function TEXT Choices('sqrt', 'log', 'clr')
The method applied to transform feature values before
generating volcano plots. [default: 'clr']
--p-difference-function TEXT Choices('mean_difference', 'f_statistic')
The method applied to visualize fold difference in
feature abundances across groups for volcano plots.
[optional]
--p-filter-missing / --p-no-filter-missing
If True, samples with missing metadata values will be
filtered from the table prior to analysis. If False, an
error will be raised if there are any missing metadata
values. [default: False]
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.
Import:
from qiime2.plugins.composition.visualizers import ancom
