GPIV_PIV2VEC(1) 					      General Commands Manual						   GPIV_PIV2VEC(1)

NAME
gpiv_piv2vec - Converting of PIV data. SYNOPSIS
gpiv_piv2vec [-al length] [-au units] [-flipx] [-flipy] [-g] [-h | fB--help] [-nd] [-k] [-p | --print] [-s scale] [-tl label] [-v | fB--version] [-xl label] [-yl label] [filename] < stdin > stdout DESCRIPTION
gpiv_piv2vec adds an header to piv data for a vector plot with Plotmtv. This program does not use the parameter resources from libgpiv. Options -al length Plots a vector annotation of length. -au units Plots a vector annotation of units. -flipx Flips the plot in x-direction; x data from high to low. -flipy Flips the plot in y-direction; y data from high to low. -g Displays piv data graphically. filename has to be defined. -h | fB--help On-line help. -nd Combined with -g; adds option -nodate (only ps output doesn't contain date!). -k Keep plot-file. -p | --print Plots the output on screen with Plotmtv if filename has been used. -s scale Vector scale (default: 1 px). -tl label Defines top label (title) (default: filename, if used). -v | fB--version Prints version information on standard output, then exits successfully. -xl label Defines x-label (default: "x (pixels)"). -yl label Defines y-label (default: "y (pixels)"). filename Uses PIV file instead of stdin and stdout. The output will be written to filename.vec. SEE ALSO gpivtools AUTHOR
Gerber Van der Graaf BUGS
The program has been tested for PIV data. Watch out for filenames containing dots, apart from the separation with extension. 8 November 2006 GPIV_PIV2VEC(1)

NAME
gpiv_manipiv, gpiv_fasty, gpiv_flipx, gpiv_flipy, gpiv_revert, gpiv_rot90, gpiv_rot180 - Simple data manipulation tool for PIV data. SYNOPSIS
gpiv_manipiv [-h | --help] [-p | --print] [-v | --version] [-fi x0 y0 x1 y1] [-no_fi | --pass x0 y0 x1 y1] [-fy] [-r] [--rev] [-x] [-y] [filename] < stdin > stdout DESCRIPTION
gpiv_manipiv manipulates order and positions of PIV data, mirrors (flips) the data in horizontal (x) or vertical (y) direction, rotates over 90 and 180 degrees. As rotating over 180 degrees is identic to flipping over x as well as over y-direction, the program must be called twice or must be called once by rot180. The parameters read from the configuration resources (containing the key POST) may be overruled by the command line options, as explained below. In case an alias name of gpiv_manipiv has been used, all non-relevant parameters are disabled. Options -fi x0 y0 x1 y1 filters out data from a piv data stream from location (x0,y0) to (x1,y1). Filtering only implies setting the peak number to -1. -no_fi | --pass x0 y0 x1 y1 filters out all data, except those from (x0,y0) to (x1,y1). This option is the opposite of -fi. Filtering only implies setting the peak number to -1. -fy Returns fast running y-positions of data that are originally written with fast running x-positions. All other variables (particle displacements, snr, peak#) are at the new positions, too. Identic to fasty. -h | --help On-line help. -p | --print Prints parameters, command line options and input and output filenames to stdout. The output is identic of filename.par, in case -f is used. -r Rotates the data over 90 degrees. Identic to rot90. --rev Reverts array indexes of output data for getting reversed order. This results into high to low running positions or vice versa. Identic to revert. -v | --version Print version information on standard output, then exits successfully. -x Flips the data in x-direction (vertical axis). Identic to flipx. -y Flips the data in y-direction (horizontal axis). Identic to flipy. filename Input PIV data file. Overrides stdin and stdout. Output will be written to filename.ma.piv. The parameters will be written or appended to filename.par and may be used for future use by including them in ./gpivrc. SEE ALSO gpivtools AUTHOR
