NAME

       h4fromh5 - convert HDF5 scientific dataset to an HDF4 file

SYNOPSIS

       h4fromh5 [OPTIONS] [HDF5-FILES]

DESCRIPTION

       h4fromh5  takes one or more files in HDF5 format and outputs files in HDF4 format containing the datasets
       from the HDF5 files.  (Currently, only a single dataset per HDF5 file is converted.)

       HDF4 and HDF5 are free, portable binary formats and supporting libraries developed by the National Center
       for Supercomputing Applications at the University of Illinois in Urbana-Champaign.

       A  single  h5  file  can contain multiple data sets; by default, h4fromh5 converts the first dataset, but
       this can be changed via the -d option, or by using the syntax HDF5FILE:DATASET.

       The most basic usage is something like ’h4fromh5 foo.h5’, which will output a file foo.hdf containing the
       scientific dataset from foo.h5.

OPTIONS

       -h     Display help on the command-line options and usage.

       -V     Print the version number and copyright info for h4fromh5.

       -v     Verbose output.

       -T     Transpose  the  output  dataset  (e.g.  LxMxN  becomes  NxMxL).  This is often useful because HDF5
              programs typically follow C (row-major) conventions  while  HDF4  programs  often  follow  Fortran
              (column-major, transposed) conventions for array ordering.

       -o file
              Send  HDF  output  to  file  rather  than  to  the input filename with .h5 replaced with .hdf (the
              default).

       -d name
              Read from dataset name in the input; otherwise, the first dataset  in  the  input  file  is  used.
              Alternatively, use the syntax HDF5FILE:DATASET when the input file names are specified.
