GPIV_VHISTO(1) General Commands Manual GPIV_VHISTO(1)NAME
gpiv_vhisto - Tests PIV data by printing/displaying an histogram of the vertical particle displacements.
SYNOPSIS
gpiv_vhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
Gpiv_vhisto calculates the histogram of the vertical particle displacement distribution between minimum and maximum values.
The parameters read from the configuration resources (containing the key VALID) may be overruled by the command line options, as explained
below.
Options-g Graphical visualization of the histogram with gnuplot.
-h | --help
On-line help
-n N Override number of bins (default 10, hard coded).
-p | --print
Print parameters, command line options and eventually used input and output filenames to stdout. The output is identic of file-
name.par, in case -f is used.
-v | --version
Print version information on standard output, then exit successfully.
filename
Input PIV file. Overrides stdin and stdout. Output will be written to filename.pdf. The parameters will be written or appended to
filename.par and may be used for future use by including them in ./gpivrc.
SEE ALSO
gpivtools
NOTES
stdin and stdout has still to be implemented. [-f filename ] will be added.

Gerber Van der Graaf
BUGS
The program seems to work fine with real PIV data. So far, no serious bugs have been found.

GPIV_ROT180(1) General Commands Manual GPIV_ROT180(1)NAME
gpiv_rot180 - Simple data manipulation tool for PIV data.
SYNOPSIS
gpiv_rot180 [-h | --help] [-p | --print] [-p | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_rot180 rotates the data over 180 degrees. As rotating over 180 degrees is identic to flipping over x as well as over y-direction,
flipx and flipy may be used instead of gpiv_rot180.
The parameters read from the configuration resources (containing the key POST) may be overruled by the command line options, as explained
below.
Options-h | --help
On-line help.
-p | --print
Prints parameters, command line options and input and output filenames to stdout. The output may be used as parameters of
gpiv_rot180 for future use by re-directing stdout to gpiv_rot180.par.
-v | --version
Print version information on standard output, then exits successfully.
filename
Input PIV file. Overrides stdin and stdout. Output will be written to filename.ma.piv. The parameters will be written or appended to
filename.par.

hi,
how does a program know whether some data are available from stdin?
I would like to make a program which could read its data from stdin
and _if_there_is_nothing_at_stdin_ from a file which name is given
as an argument. If there is nothing in stdin and no filename is given as
