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.
