Hello H. Joe Lee, I am not the original author of the HDF5 Java code, but looking at [1] and [2], it's pretty clear that netcdf-java only supports gzip, shuffle, and fletcher32. It seems like there were also plans for "szip", "nbit", and "scaleoffset", but that functionality hasn't been implemented. Cheers, Christian [1] https://github.com/Unidata/thredds/blob/v4.6.1/cdm/src/main/java/ucar/nc2/iosp/hdf5/H5header.java#L3632 [2] https://github.com/Unidata/thredds/blob/v4.6.1/cdm/src/main/java/ucar/nc2/iosp/hdf5/H5tiledLayoutBB.java#L191 On Wed, May 27, 2015 at 9:39 AM, H.
