S - is an integer U - is a filename. T - is an integer A - is an integer greater than zero Q - is the sort index type for the input file. It can be "name" or "creation_order" (default) Z - is the sort order type for the input file. It can be "descending" or "ascending" (default) B - is the user block size, any value that is 512 or greater and is a power of 2 (1024 default) F - is the shared object header message type, any of . If F is not specified, S applies to all messages BOUND is an integer indicating the library release versions to use when creating objects in the file (see H5Pset_libver_bounds()): 0: This is H5F_LIBVER_EARLIEST in H5F_libver_t struct 1: This is H5F_LIBVER_V18 in H5F_libver_t struct 2: This is H5F_LIBVER_V110 in H5F_libver_t struct 3: This is H5F_LIBVER_V112 in H5F_libver_t struct 4: This is H5F_LIBVER_V114 in H5F_libver_t struct (H5F_LIBVER_LATEST is aliased to H5F_LIBVER_V114 for this release FS_STRATEGY is a string indicating the file space strategy used: FSM_AGGR: The mechanisms used in managing file space are free-space managers, aggregators and virtual file driver. PAGE: The mechanisms used in managing file space are free-space managers with embedded paged aggregation and virtual file driver. AGGR: The mechanisms used in managing file space are aggregators and virtual file driver. NONE: The mechanisms used in managing file space are virtual file driver. The default strategy when not set is FSM_AGGR without persisting free- space. FS_PERSIST is 1 to persisting free-space or 0 to not persisting free-space. The default when not set is not persisting free-space. The value is ignored for AGGR and NONE strategies. FS_THRESHOLD is the minimum size (in bytes) of free-space sections to be tracked by the library. The default when not set is 1. The value is ignored for AGGR and NONE strategies. FS_PAGESIZE is the size (in bytes) >=512 that is used by the library when the file space strategy PAGE is used. The default when not set is 4096. FILT - is a string with the format: := is a comma separated list of object names, meaning apply compression only to those objects. If no names are specified, the filter is applied to all objects can be: GZIP, to apply the HDF5 GZIP filter (GZIP compression) SZIP, to apply the HDF5 SZIP filter (SZIP compression) SHUF, to apply the HDF5 shuffle filter FLET, to apply the HDF5 checksum filter NBIT, to apply the HDF5 NBIT filter (NBIT compression) SOFF, to apply the HDF5 Scale/Offset filter UD, to apply a user defined filter NONE, to remove all filters is optional filter parameter information GZIP= from 1-9 SZIP= pixels per block is a even number in 2-32 and coding method is either EC or NN SHUF (no parameter) FLET (no parameter) NBIT (no parameter) SOFF= scale_factor is an integer and scale_type is either IN or DS UD= Required values: filter_number, filter_flag, cd_value_count, value1 Optional values: value2 to valueN filter_flag: 1 is OPTIONAL or 0 is MANDATORY NONE (no parameter) LAYT - is a string with the format: := is a comma separated list of object names, meaning that layout information is supplied for those objects. If no names are specified, the layout type is applied to all objects can be: CHUNK, to apply chunking layout COMPA, to apply compact layout CONTI, to apply contiguous layout is optional layout information CHUNK=DIM[xDIM...xDIM], the chunk size of each dimension COMPA (no parameter) CONTI (no parameter) Examples of use: 1) h5repack -v -f GZIP=1 file1 file2 GZIP compression with level 1 to all objects 2) h5repack -v -f dset1:SZIP=8,NN file1 file2 SZIP compression with 8 pixels per block and NN coding method to object dset1 3) h5repack -v -l dset1,dset2:CHUNK=20x10 -f dset3,dset4,dset5:NONE file1 file2 Chunked layout, with a layout size of 20x10, to objects dset1 and dset2 and remove filters to objects dset3, dset4, dset5 4) h5repack -L -c 10 -s 20:dtype file1 file2 Using latest file format with maximum compact group size of 10 and minimum shared datatype size of 20 5) h5repack -f SHUF -f GZIP=1 file1 file2 Add both filters SHUF and GZIP in this order to all datasets 6) h5repack -f UD=307,0,1,9 file1 file2 Add bzip2 filter to all datasets 7) h5repack --low=0 --high=1 file1 file2 Set low=H5F_LIBVER_EARLIEST and high=H5F_LIBVER_V18 via H5Pset_libver_bounds() when creating the repacked file, file2
