h4fromh5 - convert HDF5 scientific dataset to an
HDF4 file
h4fromh5 [OPTION]... [HDF4FILE]...
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.
- -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.
