gpiv_s-avg(1)

Usage

gpiv_s-avg [{-h | --help}] [{-p | --print}] [-s] [-no_s] [{-v | --version}] [filename] < stdin > stdout

Overview

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.
