[Bioc-devel] Error in HDF5 - Package submission - Not detected locally

I suspect what has happened here is that when create the mini_pbmc3k
object, you're doing this by subsetting the PBMC, 3k scRNA-seq data from
ExperimenHub. The assay data for that are are actually stored in an HDF5
file which will be downloaded and stored in your ExperimentHub cache on
your local machine. When you take the subset for your new object it still
points to the same HDF5 file, and when you save mini_pbmc3k all it actually
saves is the location of the HDF5 rather than putting the data in the
object. This works locally, but naturally the BioC build server doesn't
have the original HDF5 in exactly the same location, and so it fails.
Is there a reason you don't want to use the whole dataset and make the
first section of the vignette demonstrate how to download it via
ExperimentHub? Alternatively there is a way to transform from an HDF5 back
SingleCellExperiment to using the data in memory, but I can't remember it
right now - hopefully someone else will be along shortly.
This also seems like the perfect opportunity to point out that our next
BioC Developers' Forum (
have a discussion on object serilaisation which should cover exactly this
type of issue.
