DropletTestFiles 1.15.0
The DropletTestFiles package contains files for testing droplet-based utilities, such as those in the DropletUtils package. These files are literally the raw output of pipelines like 10X Genomics’ CellRanger software suite, and are usually not in an (immediately) analysis-ready state. After all, the idea is to provide some material to test the utilities to get to such a state!
This package doesn’t do anything except pull down and serve up files, so there’s not much to talk about here. There are two convenience functions to help obtain content from ExperimentHub. The first is to list all available resources managed by DropletTestFiles:

## "/home/biocbuild/.cache/R/ExperimentHub/171af3261fe38d_3721"Currently, all of the files come from 10X Genomics datasets. As such, we will see a lot of filtered/raw count matrices, molecule information files and HDF5 barcode matrices. We refer readers to the (relevant section)[https://support.10xgenomics.com/single-cell-gene-expression/software/pipelines/latest/output/overview] of the 10X Genomics website for more details.
Here, we obtain a path to a filtered HDF5 matrix and read it in with a DropletUtils function.
This produces a SingleCellExperiment object for use in various Bioconductor pipelines.
