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 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.
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 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.
