NAME

       h5totxt - generate comma-delimited text from 2d slices of HDF5 files

SYNOPSIS

       h5totxt [OPTION]... [HDF5FILE]...

DESCRIPTION

       h5totxt is a utility to generate comma-delimited text (and similar formats) from one-, two-, or more-dimensional slices of numeric datasets
       in HDF5 files.  This way, the data can easily be imported into spreadsheets and similar programs for analysis and visualization.

       HDF5 is a free, portable binary format and supporting library developed by the National Center for Supercomputing Applications at the  Uni-
       versity of Illinois in Urbana-Champaign.  A single h5 file can contain multiple data sets; by default, h5totxt takes the first dataset, but
       this can be changed via the -d option, or by using the syntax HDF5FILE:DATASET.

       By default, the entire dataset is dumped to the output.	in row-major order.  For 3d datasets, this corresponds to a sequence of yz slices,
       in order of increasing x, separated by blank lines.  If -T is specified, outputs in the transposed (column-major) order instead

       Often,  however,  you  want  only a one- or two-dimensional slice of multi-dimensional data.  To do this, you specify coordinates in one or
       more slice dimensions, via the -xyzt options.

       The most basic usage is something like 'h5totxt foo.h5', which will output comma-delimited text to stdout from the data in foo.h5.

OPTIONS

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

       -V     Print the version number and copyright info for h5totxt.

       -v     Verbose output.

       -o file
	      Send text output to file rather than to stdout (the default).

       -s sep Use the string sep to separate columns of the output rather than a comma (the default).

       -x ix, -y iy, -z iz, -t it
	      This tells h5totxt to use a particular slice of a multi-dimensional dataset.  e.g.  -x causes a yz plane (of a  3d  dataset)  to	be
	      used,  at an x index of ix (where the indices run from zero to one less than the maximum index in that direction).  Here, x/y/z cor-
	      respond to the first/second/third dimensions of the HDF5 dataset. The -t option specifies a slice in the last  dimension,  whichever
	      that might be.  See also the -0 option to shift the origin of the x/y/z slice coordinates to the dataset center.

       -0     Shift  the  origin  of  the x/y/z slice coordinates to the dataset center, so that e.g. -0 -x 0 (or more compactly -0x0) returns the
	      central x plane of the dataset instead of the edge x plane.  (-t coordinates are not affected.)

       -T     Transpose the data (interchange the dimension ordering).	By default, no transposition is done.

       -. numdigits
	      Output numdigits digits after the decimal point (defaults to 16).

       -d name
	      Use dataset name from the input files; otherwise, the first  dataset  from  each	file  is  used.   Alternatively,  use  the  syntax
	      HDF5FILE:DATASET,  which allows you to specify a different dataset for each file.  You can use the h5ls command (included with hdf5)
	      to find the names of datasets within a file.

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.
