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
libgpiv.
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 respectively 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.
