apply_median_filtering: apply_median_filtering
In infercnv: Infer Copy Number Variation from Single-Cell RNA-Seq Data

Description Usage Arguments Value Examples

Apply a median filtering to the expression matrix within each tumor bounds

apply_median_filtering(
  infercnv_obj,
  window_size = 7,
  on_observations = TRUE,
  on_references = TRUE
)

`infercnv_obj`	infercnv_object
`window_size`	Size of the window side centered on the data point to filter (default = 7).
`on_observations`	boolean (default=TRUE), run on observations data (tumor cells).
`on_references`	boolean (default=TRUE), run on references (normal cells).
