apply_median_filtering {infercnv} | R Documentation |
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). |
