ANN2FIG(1) User Commands ANN2FIG(1)NAME
ann2fig - Dump ANN tree structure in Fig format
SYNOPSIS
ann2fig [-upi scale] [-x low_x] [-y low_y]
[-sz size] [-dx dim_x] [-dy dim_y] [-sl dim value]*
[-ps pointsize] file
DESCRIPTION
This program inputs an ann dump file of a search structure perhaps along with point coordinates, and outputs a fig (Ver 3.1) file (see
fig2dev (1)) displaying the tree. The fig file may then be displayed using xfig, or converted to any of a number of other formats using
fig2dev.
If the dimension is 2 then the entire tree is displayed. If the dimension is larger than 2 then the user has the option of selecting which
two dimensions will be displayed, and the slice value for each of the remaining dimensions. All leaf cells intersecting the slice are
shown along with the points in these cells.
OPTIONS -upi scale
fig units per inch (default = 1200)
-x low_x -y low_y
x and y offset of upper left corner (inches) (default = 1)
-sz size
maximum side length of figure (in inches) (default = 5)
-dx dim_x
horizontal dimension (default = 0)
-dy dim_y
vertical dimension (default = 1)
-sv value
default slice value (default = 0)
-sl dim value
each such pair defines the value along the given dimension at which to slice. This may be supplied for all dimensions except dim_x and
dim_y.
-ps pointsize
size of points in fig units (def = 10)
file
file (input=file.dmp, output=file.fig)

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.
