H5FROMH4(1) h5utils H5FROMH4(1) NAME h5fromh4 - convert HDF4 scientific datasets to an HDF5 file SYNOPSIS h5fromh4 [OPTION]... [HDF4FILE]... DESCRIPTION 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 cre- ates 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" suf- fix) used as the dataset names. The most basic usage is something like 'h5fromh4 foo.hdf', which will out- put a file foo.h5 containing the scientific dataset from foo.hdf. OPTIONS -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 spec- ified, 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. BUGS Send bug reports to S. G. Johnson, stevenj@alum.mit.edu. AUTHORS Written by Steven G. Johnson.
