alpha-rarefaction: Alpha rarefaction curvesΒΆ

Docstring:

Usage: qiime diversity alpha-rarefaction [OPTIONS]

  Generate interactive alpha rarefaction curves by computing rarefactions
  between `min_depth` and `max_depth`. The number of intermediate depths to
  compute is controlled by the `steps` parameter, with n `iterations` being
  computed at each rarefaction depth. If sample metadata is provided, samples
  may be grouped based on distinct values within a metadata column.

Inputs:
  --i-table ARTIFACT FeatureTable[Frequency]
                          Feature table to compute rarefaction curves from.
                                                                    [required]
  --i-phylogeny ARTIFACT  Optional phylogeny for phylogenetic metrics.

Parameters:
  --p-max-depth INTEGER   The maximum rarefaction depth. Must be greater than
    Range(1, None)        min-depth.                                [required]

  --p-min-depth INTEGER   The minimum rarefaction depth.

  --p-steps INTEGER       The number of rarefaction depths to include between
    Range(2, None)        min-depth and max-depth.               [default: 10]
  --p-iterations INTEGER  The number of rarefied feature tables to compute at
    Range(1, None)        each step.                             [default: 10]

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.

Alpha rarefaction curves

Generate interactive alpha rarefaction curves by computing rarefactions
between `min_depth` and `max_depth`. The number of intermediate depths to
compute is controlled by the `steps` parameter, with n `iterations` being
computed at each rarefaction depth. If sample metadata is provided, samples
may be grouped based on distinct values within a metadata column.
