NAME

       aida2flat - Convert AIDA data files to a flat format

SYNOPSIS

       aida2flat [options] aidafile [aidafile2 ...]

DESCRIPTION

       Convert	AIDA  data  files  to  a  flat	format	which  is  more  human-readable then the XML (and by default also plottable directly using
       make-plots). The output is by default written out to standard output unless the --split, --smart-output, --gnuplot, or --output options are
       specified. When specifying either input or output filenames, a '-' is used to refer to stdin or stdout as appropriate.

       Histograms can also be filtered by AIDA path, using the -m or -M options for a positive or negative regex pattern patch respectively.

OPTIONS

       -h, --help
	      show this help message and exit

       -o OUTPUT, --output=OUTPUT
	      Write  all  histos to a single output file, rather than the default writing to stdout. stdout can be explicitly specified by setting
	      '-' as the output filename. This option will be disregarded if --split, --smart-output, or --gnuplot is specified.

       -s, --split
	      Write each histo to a separate output file, with names based on the histo path

       -S, --smart-output
	      Write to output files with names based on the corresponding input filename. This option will be disregarded if --split is specified.

       -g, --gnuplot
	      Provide output suitable for Gnuplot's 'plot "foo.dat" with  xye'.  This  option  implies	--split  and  will  override  --output	or
	      --smart-output

       --plotinfodir=PLOTINFODIR
	      directory which may contain plot header information

       -m PATHPATTERNS, --match=PATHPATTERNS
	      Only write out histograms whose $path/$name string matches these regexes

       -M PATHUNPATTERNS, --unmatch=PATHUNPATTERNS
	      Exclude histograms whose $path/$name string matches these regexes

GPIV_VORSTRA(1) 					      General Commands Manual						   GPIV_VORSTRA(1)

NAME

       gpiv_vorstra - Calculates the differential quantities vorticity, shear strain and normal strain from PIV data.

SYNOPSIS

       gpiv_vorstra [-d N] [-h | --help] [-n | -o | -s] [--no_g ] [-p | --print] [-g | --g] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_vorstra  calculates the differential quantities like vorticity, shear strain and normal strain from PIV data. You can choose from sev-
       eral differential schemes: central differentiation, least squares, Richardson extrapolation and circulation method. Circulation method only
       allows one to calculate vorticity, but no strain. The output can be generated as ASCII data containing four columns or as GNUPlot Data for-
       mat 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

       -n     Calculate  normal  strain  of the PIV data. As an alternative the program may be called by its nickname gpiv_nstrain. In combination
	      with filename the output will be written to filename.nstr.

       -o     Calculate vorticity of the PIV data. As an alternative the program may be called by its nickname	gpiv_vorty.  In  combination  with
	      filename the output will be written to filename.vor.

       -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.

       -s     Calculate shear strain of the PIV data. As an alternative the program may be called by its nickname  sstrain.  In  combination  with
	      filename the output will be written to filename.sstr.

       -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.vor with -o, filename.nstr with -n or file-
	      name.sstr with -s.  Parameters are stored in filename.par and may be used for future use by including them in ./gpivrc.
