gpiv_flipx - Simple data manipulation tool for PIV data.
SYNOPSIS
gpiv_flipx [-h | --help] [-p | --print] [-v | --version] [filename] < stdin > stdout
DESCRIPTION
gpiv_flipx flips the data in x-direction (vertical axis).
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_flipx
for future use by re-directing stdout to gpiv_flipx.par.
-v | --version
Print version information on standard output, then exits successfully.
filename
Input PIV data file. Overrides stdin and stdout. Output will be written to filename.ma.piv. The parameters will be written or

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.
