\title{Get 10x cell statistics}
\description{Compute some basic per-cell statistics from the 10x molecule information file.}

\usage{
get10xMolInfoStats(sample, barcode.length=NULL)
}

\arguments{
\item{sample}{A string containing the path to the molecule information HDF5 file.}
\item{barcode.length}{An integer scalar specifying the length of the cell barcode, see \code{\link{read10xMolInfo}}.}
}

\value{
A DataFrame containing one row per cell library, with the fields:
\describe{
    \item{\code{cell}:}{Character, the cell barcode.}
    \item{\code{gem_group}:}{Integer, the GEM group.}
    \item{\code{num.umis}:}{Integer, the number of UMIs assigned to this cell barcode/GEM group combination.}
    \item{\code{num.reads}:}{Integer, the number of reads for this combination.}
    \item{\code{num.genes}:}{Integer, the number of detected genes.}
}
