This function downloads the processed data for the experiment documented
at https://github.com/LieberInstitute/Human_DLPFC_Deconvolution.
Internally, this function downloads the data from ExperimentHub.
fetch_deconvo_data(
type = c("rse_gene", "sce", "sce_DLPFC_example"),
destdir = tempdir(),
eh = ExperimentHub::ExperimentHub(),
bfc = BiocFileCache::BiocFileCache()
)A character(1) specifying which file you want to download.
rse_gene: A RangedSummarizedExperiment-class
with 110 bulk RNA-seq samples x 21k genes. (41 MB)
sce: A SingleCellExperiment
object with Human DLPFC snRNA-seq data. 77k nuclei x 36k genes (172 MB)
sce_DLPFC_example: An example subset of sec
SingleCellExperiment
with 10k nuclei x 557 genes (49 MB)
The destination directory to where files will be downloaded
to in case the ExperimentHub resource is not available. If you already
downloaded the files, you can set this to the current path where the files
were previously downloaded to avoid re-downloading them.
An ExperimentHub object
ExperimentHub-class.
A BiocFileCache object
BiocFileCache-class. Used when
eh is not available.
The requested object: rse_gene that you assign to an object
We are currently waiting for https://doi.org/10.1101/2024.02.09.579665 to
pass peer review at a journal, which could lead to changes requested by the
peer reviewers on the processed data for this study. Thus, this function
temporarily downloads the files from Dropbox using
BiocFileCache::bfcrpath() unless the files are present already at
destdir.
Note that ExperimentHub and BiocFileCache will cache the data and
automatically detect if you have previously downloaded it, thus making it
the preferred way to interact with the data.
This function is based on spatialLIBD::fetch_data().
