DESCRIPTION
Convert a generic NetCDF file into a PyTables (HDF5 format) file
OPTIONS
A summary of options is included below.
- -h
-
Prints a help text.
- -v
-
Show more information.
- -o
-
Overwrite destination file.
- --complevel=(0-9)
-
Sets a compression level (0 for no compression, which is the default).
- --complib=lib
-
Sets the compression library to be used during the copy. lib can
be set to "zlib", "lzo" or "ucl". Defaults to "zlib".
- --shuffle=(0|1)
-
Activate or not the shuffling filter (default is active if complevel>0).
- --fletcher32=(0|1)
-
Whether activate or not the fletcher32 filter (not active by default).
- --unpackshort=(0|1)
-
Unpack short integer variables to float variables using scale_factor
and add_offset netCDF variable attributes (not active by default).
- --quantize=(0|1)
-
Quantize data to improve compression using least_significant_digit
netCDF variable attribute (not active by default). See
http://www.cdc.noaa.gov/cdc/conventions/cdc_netcdf_standard.shtml
for further explanation of what this attribute means.
