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

NAME
gpiv_rot180 - Simple data manipulation tool for PIV data. SYNOPSIS
gpiv_rot180 [-h | --help] [-p | --print] [-p | --version] [filename] < stdin > stdout DESCRIPTION
gpiv_rot180 rotates the data over 180 degrees. As rotating over 180 degrees is identic to flipping over x as well as over y-direction, flipx and flipy may be used instead of gpiv_rot180. 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_rot180 for future use by re-directing stdout to gpiv_rot180.par. -v | --version Print version information on standard output, then exits successfully. filename Input PIV file. Overrides stdin and stdout. Output will be written to filename.ma.piv. The parameters will be written or appended to filename.par. SEE ALSO
