Convert a Seurat object (or RDS/H5Seurat file) to an AnnData object file

Usage

ConvertSeuratToAnnData(
  object_or_file,
  outfile,
  assay = NULL,
  subset = NULL,
  log = NULL
)

Arguments

object_or_file: The Seurat object or the path to the RDS or H5Seurat file
outfile: Output file
assay: Assay to be used
subset: Subset of cells to be kept in the AnnData object
log: Logger

Value

No return value
