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.
