Error: Cannot find feature names in this H5AD file #7
Comments
For this specific H5AD file, it's compressed using the LZF filter. This filter is Python-specific, and cannot easily be used in R. To use this file with Seurat and SeuratDisk, you'll need to read it in Python and save it out using the gzip compression import anndata
adata = anndata.read("deprez19_restricted.processed.h5ad")
adata.write("deprez19_restricted.processed.gzip.h5ad", compression="gzip") |
