This site has been replaced by the new QIIME 2 “amplicon distribution” documentation, as of the 2025.4 release of QIIME 2. You can still access the content from the “old docs” here for the QIIME 2 2024.10 and earlier releases, but we recommend that you transition to the new documentation at https://amplicon-docs.qiime2.org.

shuffle-groups: Shuffle values in a categorical sample metadata column.¶
Docstring:
Usage: qiime metadata shuffle-groups [OPTIONS] Create one or more categorical sample metadata columns by shuffling the values in an input metadata column. To avoid confusion, the column name and values will be derived from the provided prefixes. The number of different values (or groups), and the counts of each value, will match the input metadata column but the association of values with sample ids will be random. These data will be written to an artifact that can be used as sample metadata. Parameters: --m-metadata-file METADATA --m-metadata-column COLUMN MetadataColumn[Categorical] Categorical metadata column to shuffle. [required] --p-n-columns INTEGER The number of shuffled metadata columns to create. [default: 3] --p-md-column-name-prefix TEXT Prefix to use in naming the shuffled metadata columns. [default: 'shuffled.grouping.'] --p-md-column-values-prefix TEXT Prefix to use in naming the values in the shuffled metadata columns. [default: 'fake.group.'] --p-encode-sample-size / --p-no-encode-sample-size If true, the sample size of each metadata group will be appended to the shuffled metadata column values. [default: False] Outputs: --o-shuffled-groups ARTIFACT SampleData[ArtificialGrouping] Randomized metadata columns [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. --use-cache DIRECTORY Specify the cache to be used for the intermediate work of this action. If not provided, the default cache under $TMP/qiime2/will be used. IMPORTANT FOR HPC USERS: If you are on an HPC system and are using parallel execution it is important to set this to a location that is globally accessible to all nodes in the cluster. --help Show this message and exit.
