TSSEnrichment: Compute TSS enrichment score per cell

In Honchkrow/SignacSlim: The slim version of signac

Compute TSS enrichment score per cell

Description

Compute the transcription start site (TSS) enrichment score for each cell, as defined by ENCODE: https://www.encodeproject.org/data-standards/terms/.

Usage

TSSEnrichment(
  object,
  tss.positions = NULL,
  n = NULL,
  fast = TRUE,
  assay = NULL,
  cells = NULL,
  process_n = 2000,
  verbose = TRUE
)

Arguments

object	A Seurat object
tss.positions	A GRanges object containing the TSS positions. If NULL, use the genomic annotations stored in the assay.
n	Number of TSS positions to use. This will select the first _n_ TSSs from the set. If NULL, use all TSSs (slower).
fast	Just compute the TSS enrichment score, without storing the base-resolution matrix of integration counts at each site. This reduces the memory required to store the object but does not allow plotting the accessibility profile at the TSS.
assay	Name of assay to use
cells	A vector of cells to include. If NULL (default), use all cells in the object
process_n	Number of regions to process at a time if using fast option.
verbose	Display messages

Details

The computed score will be added to the object metadata as "TSS.enrichment".

Value

Returns a Seurat object
