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. BUGS
