AdtPcaState

AdtPcaState

This step performs a principal components analysis (PCA) to compact and denoise ADT data. The resulting PCs can be used as input to various per-cell analyses like clustering and dimensionality reduction. It wraps the runPca function from scran.js.

Methods not documented here are not part of the stable API and should not be used by applications.

Description:

  • This method should not be called directly by users, but is instead invoked by runAnalysis.

Source:
Parameters:
Name Type Description
parameters object

Parameter object, equivalent to the adt_pca property of the parameters of runAnalysis.

Properties
Name Type Description
num_pcs number

Number of PCs to return.
block_method string

Blocking method to use when dealing with multiple samples. This can be "none", "regress" or "project", see comments in RnaPcaState.
Returns:

The object is updated with the new results.
