WebHDF5 Feature-Barcode Matrix Format. In addition to the MEX format, we also provide matrices in the Hierarchical Data Format (HDF5 or H5). H5 is a binary format that can compress and access data much more efficiently than text formats such as MEX, which is especially useful when dealing with large datasets. H5 files are supported in both R and ... WebHDF5 datasets re-use the NumPy slicing syntax to read and write to the file. Slice specifications are translated directly to HDF5 “hyperslab” selections, and are a fast and efficient way to access data in the file. The following slicing arguments are recognized: Indices: anything that can be converted to a Python long Slices (i.e. [:] or [0:10])
