Usage: qiime diversity filter-distance-matrix [OPTIONS]
Filter samples from a distance matrix, retaining only the samples matching
search criteria specified by `metadata` and `where` parameters (or retaining
only the samples not matching that criteria, if `exclude_ids` is True). See
the filtering tutorial on https://docs.qiime2.org for additional details.
Inputs:
--i-distance-matrix ARTIFACT
DistanceMatrix Distance matrix to filter by sample. [required]
Parameters:
--m-metadata-file METADATA...
(multiple Sample metadata used with `where` parameter when
arguments will selecting samples to retain, or with `exclude-ids` when
be merged) selecting samples to discard. [required]
--p-where TEXT SQLite WHERE clause specifying sample metadata
criteria that must be met to be included in the
filtered distance matrix. If not provided, all samples
in `metadata` that are also in the input distance
matrix will be retained. [optional]
--p-exclude-ids / --p-no-exclude-ids
If `True`, the samples selected by `metadata` or
`where` parameters will be excluded from the filtered
distance matrix instead of being retained.
[default: False]
Outputs:
--o-filtered-distance-matrix ARTIFACT
DistanceMatrix Distance matrix filtered to include samples matching
search criteria [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.

Parameters
----------

all samples in `metadata` that are also in the input distance matrix
will be retained.
exclude_ids : Bool, optional
If `True`, the samples selected by `metadata` or `where` parameters

retained.
Returns
-------
filtered_distance_matrix : DistanceMatrix
Distance matrix filtered to include samples matching search criteria
