Extract `adata.obs_names` from an H5AD file

Source: R/hdf5Access.R
readH5ADObsNames.Rd

It frequently happens that velocity analyses stored in H5AD files do not contain the full raw count data suggested for CytoSimplex visualization. Extracting the cell IDs (e.g. barcodes) helps matching the velocity data to raw count data imported from other sources.

Usage

readH5ADObsNames(filename)

Arguments

filename

File path to the H5AD file.

Value

A character vector of cell IDs.

Examples

if (FALSE) {
h5adFile <- "path/to/analysis.h5ad"
cellIDs <- readH5ADObsNames(h5adFile)
}
