GPIV_PIV2GNUPLT(1)					      General Commands Manual						GPIV_PIV2GNUPLT(1)

NAME

       gpiv_piv2gnuplt - Converts PIV data gnuplot data.

SYNOPSIS

       gpiv_piv2gnuplt [-al int] [-au int] [-h | --help] [-p | --print] [-s float] [-v | --version] [-z] filename

DESCRIPTION

       gpiv_piv2gnuplt converts PIV data to gnuplot vectors for displaying and printing PIV the estimators in a graphical way.

       This  program  does  not  use  the parameter resources from libgpiv. The parameters may be defined by the command line options as explained
       below.

Options
       -al  L Draws an annotation vector with length L.

       -al  UNIT
	      Define unit of annotation vector (defaul m/s).

       -h | --help
	      On-line help.

       -p | --print
	      Prints parameters to stdout.

       -s  SCALE
	      Scale factor for graphic output with gnuplot.

       -v | --version
	      Print version information on standard output, then exits successfully.

       -z     Full zoom (for scaled data).

       filename
	      Filename containing the input PIV data.

NAME

       gpiv_nstrain - Calculates normal strain from PIV data.

SYNOPSIS

       gpiv_nstrain [-d N] [-h | --help] [-p | --print] [-g | --g] [--no_g ] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_nstrain  calculates  the normal strain from PIV data. You can choose from several differential schemes: central differentiation, least
       squares, and Richardson extrapolation. The output can be generated as ASCII data containing four columns or as  GNUPlot	Data  format  that
       allows one to view/print the data as contour plots.

       The configuration parameters (containing the POST key) may be overruled by the command line options, as explained below.

Options
       -d N   Differential  type  to  be  used:  central difference (N=0), least squares (N=1), Richardson interpolation (N=2), circulation method
	      (N=3)

       -h | --help
	      On-line help

       -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 filename is used.

       -g     Show contour plot of the output with gnuplot.

       --no_g Suppresses to show contour plot of the output with gnuplot.

       -v | --version
	      Print version information on standard output, then exit successfully.

       filename
	      Input PIV data file. Overrides stdin and stdout. The output will be written to filename.nstr.  Parameters are stored in filename.par
	      and may be used for future use by including them in ./gpivrc.
