 #### H5Z-SZ3
+* Located in 'tools/H5Z-SZ3'
+* Please add "-DBUILD_H5Z_FILTER=ON" to enable this function for CMake.
+* sz3ToHDF5 and HDF5ToSz3 are provided for testing.
 
-* Use examples/print_h5repack_args.c to construct the cd_values parameters based on the specified error configuration.
-
-* Compression example: 
-`h5repack -f UD=32024,0,5,0,981668463,0,0,0 -i ~/Data/CESM-ATM-tylor/1800x3600/CLDLOW_1_1800_3600.dat.h5 -o ~/Data/CESM-ATM-tylor/1800x3600/CLDLOW_1_1800_3600.dat.sz3.h5`
-
-* Decompression example:
-`h5repack -f NONE -i ~/Data/CESM-ATM-tylor/1800x3600/CLDLOW_1_1800_3600.dat.sz3.h5 -o ~/Data/CESM-ATM-tylor/1800x3600/CLDLOW_1_1800_3600.dat.sz3.out.h5`
-
-* Alternatively, the error bound information can also be given through sz3.config (when there are no cd_values for h5repack). Example (You need to put sz3.config in the current local directory so that it will read sz3.config to get error bounds):
-`h5repack -f UD=32024,0 -i ~/Data/CESM-ATM-tylor/1800x3600/CLDLOW_1_1800_3600.dat.h5 -o ~/Data/CESM-ATM-tylor/1800x3600/CLDLOW_1_1800_3600.dat.sz3.h5`

 ## Citations
 
 **Kindly note**: If you mention SZ in your paper, the most appropriate citation is including these three references (**TBD22, ICDE21, Bigdata18**), because they cover the design and implementation of the latest version of SZ.
