\title{Obtain the Ernst spermatogenesis data}
\usage{
ErnstSpermatogenesisData(
  method = c("emptyDrops", "Cellranger"),
  location = TRUE
)
}
\arguments{
\item{method}{String indicating which cell caller to obtain results for.}

\item{location}{Logical scalar indicating whether genomic coordinates should be returned.}
}
\value{
A \linkS4class{SingleCellExperiment} object with a single matrix of UMI counts.
}
\description{
Obtain the mouse spermatogenesis single-cell RNA-seq dataset from Ernst et al. (2019).
}
\details{
This study contains two analyses done with datasets from different cell calling algorithms.
One uses Cellranger version 2 while the other uses \code{emptyDrops} from \pkg{DropletUtils}.

Column metadata includes sample information, per-cell QC metrics and cell type labels.
In particular, the sample label specifies the developmental stage of the mouse.

Note that \code{method="Cellranger"} contains additional data for Tc1 mice.
These mice have an additional human chromosome 21 inserted alongside the usual mouse chromosomes.

If \code{location=TRUE}, the coordinates of the Ensembl gene models are stored in the \code{\link{rowRanges}} of the output.

All data are downloaded from ExperimentHub and cached for local re-use.
Specific resources can be retrieved by searching for \code{scRNAseq/ernst-spermatogenesis}.
