       h5fromh4 - convert HDF4 scientific datasets to an HDF5 file


       h5fromh4 [OPTION]... [HDF4FILE]...


       h5fromh4  takes  one  or more files in HDF4 format and outputs files in
       HDF5 format containing the datasets from the HDF4  files.   (Currently,
       only a single dataset per HDF4 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, h5fromh4
       creates a dataset called "data", but this can be  changed  via  the  -d
       option,  or  by  using  the syntax HDF5FILE:DATASET with the -o option.
       The -a option can be used to append new datasets to  an  existing  HDF5
       file.   If the -o option is used and multiple HDF4 files are specified,
       all the HDF4 datasets are output into that HDF5  file  with  the  input
       filenames (minus the ".hdf" suffix) used as the dataset names.

       The  most  basic usage is something like ´h5fromh4 foo.hdf´, which will
       output a file foo.h5 containing the scientific dataset from foo.hdf.


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

       -V     Print the version number and copyright info for h5fromh4.

       -v     Verbose output.

       -a     If the HDF5 output file already exists, append the data as a new
              dataset rather than overwriting the file (the default behavior).
              An existing  dataset  of  the  same  name  within  the  file  is
              overwritten, however.

       -o file
              Send  HDF5 output to file rather than to the input filename with
              .hdf replaced with .h5 (the default).  If multiple  input  files
              were  specified,  this causes all input datasets to be stored in
              file (rather than in separate files), with the  input  filenames
              (minus the .hdf suffix) as the dataset names.

       -d name
              Write  to  dataset  name  in  the  output; otherwise, the output
              dataset is called "data" by  default.   Alternatively,  use  the
              syntax HDF5FILE:DATASET with the -o option.
