Calculates the following QC metric:

  • is_empty_drop - is the barcode an empty drop

find_cells(
  sce,
  lower = 100,
  retain = "auto",
  alpha_cutoff = 0.001,
  niters = 10000,
  expect_cells = 3000,
  ...
)

Arguments

sce

a SingleCellExperiment object

lower

see DropletUtils::emptyDrops()

retain

see DropletUtils::emptyDrops(). Use "auto" to calculate the parameter from the top expect_cells cells (cellranger method).

alpha_cutoff

The alpha cutoff used for Monte Carlo signficance.

niters

the number of Monte Carlo iterations

expect_cells

the number of cells expected for auto retain

...

additional arguments for uniformity testing

Value

sce a SingleCellExperiment object annotated with emptyDrops metrics
