Runs PHATE via Basilisk

Usage

Utility_Phate(
  x,
  sample.name,
  removestrings,
  subset,
  columns = NULL,
  notcolumns = NULL,
  subsample = NULL,
  export = FALSE,
  outpath = NULL,
  ...
)

Arguments

x: A gating set object
sample.name: Keyword for which sample name is stored
removestrings: A list of things to remove from sample.name
subset: The subset of interest from gating hierarchy
columns: A subset of columns to pass instead
notcolumns: A subset of columns to remove
subsample: If downsampling is wanted.
export: When set to TRUE returns fcs files to specified outpath.
outpath: Location to store new .fcs files
...: Additional arguments passed to Phate for fine tuning
