predict-regression: Use trained regressor to predict target values for new samples.ΒΆ

Docstring:

Usage: qiime sample-classifier predict-regression [OPTIONS]

  Use trained estimator to predict target values for new samples. These will
  typically be unseen samples, e.g., test data (derived manually or from
  split_table) or samples with unknown values, but can theoretically be any
  samples present in a feature table that contain overlapping features with
  the feature table used to train the estimator.

Inputs:
  --i-table ARTIFACT FeatureTable[Frequency | RelativeFrequency |
    PresenceAbsence | Composition]
                         Feature table containing all features that should be
                         used for target prediction.                [required]
  --i-sample-estimator ARTIFACT SampleEstimator[Regressor]
                         Sample regressor trained with fit_regressor.
                                                                    [required]
Parameters:
  --p-n-jobs NTHREADS    Number of jobs to run in parallel.       [default: 1]
Outputs:
  --o-predictions ARTIFACT SampleData[RegressorPredictions]
                         Predicted target values for each input sample.
                                                                    [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.
