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.
