GPIV_MANIPIV(1) 					      General Commands Manual						   GPIV_MANIPIV(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.

NAME

       gpiv_t-avg - Calculates time-averaged mean and variances of PIV data.

SYNOPSIS

       gpiv_t-avg  [-dn  |  --dir_name	dir  basename]	[-df  |  --first_dir  N] [-dl | --last_dir N] [-fb | --file_basename file basename] [-ff |
       --first_file N] [-fl | --last_file N] [-fx | --file_prefix] [-h | --help] [-n | --none] [-p | --print] [-relrms]  [-uv  |  --print]  [-v  |
       --version]

DESCRIPTION

       gpiv_t-avg calculates mean and variances from a series of piv data resulting into time-averaged values. If no parameters are defined at the
       command line, standard parameters will be used that are defined in the script. This program does not use the parameter resources from libg-
       piv.

Options
       -dn | --dir_name dir base-name
	      The  dir	base-name represents the directory name without its last number. It is supposed that the last number in the directory name
	      is a counter.

       -df | --first_dir
	      Defines the counter  N of the first directory number at which the analyses starts.

       -dl | --last_dir
	      Last directory number N at which the analyses ends.

       -fb | --file_base_name file base-name
	      The filename has to be given without its .piv extension. The file base-name represents the file name without its last number, before
	      the extension. If not -fx key is used, it is supposed that the last number in the file name is a counter. The output will be written
	      to dir base-name/file base-name.ta_mean.piv and dirname/filename.ta_sdev.piv at which mean values and variances are written  respec-
	      tively or to dirname/filename.ta_U.piv and to dirname/filename.ta_V.piv if -uv is used.

       -ff | --first_file
	      Defines the counter  Nof first file number at which the analyses starts.

       -fl | --last_file
	      Last file number N at which the analyses ends.

       -fx | --file_prefix
	      Prefix numbering to file base name.

       -h | --help
	      On-line help.

       -n | --none
	      Suppresses real execution.

       -p | --print
	      Prints parameters, command line options and input and output filenames to stdout.

       -relrms
	      Prints relative rms, related to the absolute mean value.

       -uv    Writes U and v displacements/velocities to separate outputs.

       -v | --version
	      Prints version information to standard output, then exits successfully.
