Usage: qiime sample-classifier classify-samples-from-dist [OPTIONS]
Run k-nearest-neighbors on a labeled distance matrix. Return cross-
validated (leave one out) predictions and accuracy. k = 1 by default
Inputs:
--i-distance-matrix ARTIFACT
DistanceMatrix a distance matrix [required]
Parameters:
--m-metadata-file METADATA
--m-metadata-column COLUMN MetadataColumn[Categorical]
Categorical metadata column to use as prediction
target. [required]
--p-k INTEGER Number of nearest neighbors [default: 1]
--p-palette TEXT Choices('YellowOrangeBrown', 'YellowOrangeRed',
'OrangeRed', 'PurpleRed', 'RedPurple', 'BluePurple', 'GreenBlue',
'PurpleBlue', 'YellowGreen', 'summer', 'copper', 'viridis', 'cividis',

'enigma', 'eros', 'spectre', 'ambition', 'mysteriousstains', 'daydream',
'solano', 'navarro', 'dandelions', 'deepblue', 'verve', 'greyscale')
The color palette to use for plotting.
[default: 'sirocco']
Outputs:
--o-predictions ARTIFACT SampleData[ClassifierPredictions]
leave one out predictions for each sample [required]
--o-accuracy-results VISUALIZATION
Accuracy results 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).
