GPIV_S-AVG(1) General Commands Manual GPIV_S-AVG(1)
NAME
gpiv_s-avg - Spatial statistics of PIV data.
SYNOPSIS
gpiv_s-avg [-h | --help] [-p | --print] [-s] [-no_s] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_s-avg reports the spatial global mean velocities and variances in x and y-direction of a PIV data stream. Only input data of which the
peak number is not equal to -1 are taken into account.
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 eventually filenames to stdout. The output is identic of filename.par, in
case -f is used.
-s Subtracts the mean x-and y-particle displacements from the input data.
-no_s Suppresses subtracting the mean values from the input data.
-v | --version
Prints version information on standard output, then exits successfully.
[-z dx0 dy0]
zero offset of displacement or velocity estimators.
filename
Input PIV file. Overrides stdin and stdout. The output will be written to filename.sa.piv. Parameters are stored in filename.par and
may be used for future use by including them in ./gpivrc.
SEE ALSO
gpivtools
NOTES
AUTHOR
Gerber Van der Graaf
BUGS
The program has been tested for PIV data. So far, no bugs have been found.
