In combiz/scFlow: A Single-Cell/Nuclei Analysis Toolkit

Generate a Pseudo-bulk SingleCellExperiment from a SingleCellExperiment

Description

Generate a pseudo-bulk of a SingleCellExperiment by summing counts of all cells from the same sample_var and celltype_var. The SCE is then re-annotated and library sizes calculated based on cell numbers.

Usage

pseudobulk_sce(
  sce,
  sample_var = "individual",
  celltype_var = "cluster_celltype",
  assay_name = "counts",
  keep_vars = c("individual", "group", "sex", "age", "PMI", "RIN", "seqdate")
)

Arguments

sce	a SingleCellExperiment object
sample_var	the variable name identifying unique samples
celltype_var	the variable name identifying cell types
assay_name	the assay name for pseudobulking (e.g. "counts")
keep_vars	metadata variables to keep from the SingleCellExperiment

Value

pb_sce a pseudobulk SingleCellExperiment object
