This function creates an expression matrix from a 10X h5 file path
get10Xmatrix_h5(path_to_data, gene_ids = c("symbols", "ensembl"))path to the 10X .h5 file
use gene symbols (default) or ensembl ids for the gene expression matrix
(list of) sparse expression matrix from 10X
If the .h5 10x file has multiple modalities (e.g. RNA and protein), multiple matrices will be returned
