  30
  31 <P>
  32 <B>t-avg</B> calculates mean and variances of a <B>set</B> of piv data
  33 resulting into time-avaraged values. If no parameters are defined at
  34 the command line, standard parameters will be used that are defined in
  35 the script.

  41 <DT><B>-dn [--dir_name] </B><I>dir base-name</I><DD>
  42 The <I>dir base-name</I> represents the directory name without its last number. It is supposed that the last number in the directory name is a counter.
  43 <DT><B>-fd [--first_dir] </B><DD>
  44 Defines the counter  <I>N</I> of the first directory number at which the analyses starts.
  45 <DT><B>-ld [--last_dir] </B><DD>
  46 Last directory number <I>N</I> at which the analyses ends.
  47 <DT><B>-fn [--file_name] </B><I>file base-name</I><DD>
  48 The <I>filename</I> has to be given without its <B>.piv</B>
  49 extension. The <I>file base-name</I> represents the file name without
  50 its last number, before the extension. It is supposed that the last
  51 number in the file name is a counter. The output will be written to
  52 <I>dir base-name/file base-name</I><B>.mpiv</B> and
  53 <I>dirname/filename</I><B>.spiv</B> at
  54 which mean values and variances are written respectively.
  55 <DT><B>-ff [--first_file] </B><DD>
  56 Defines the counter  <I>N</I>of first file number at which the analyses starts.
  57 <DT><B>-lf [--last_file] </B><DD>
  58 Last file number <I>N</I> at which the analyses ends.
  59 <DT><B>-h [--help] </B><DD>
  60 On-line help.
  61 <DT><B>-p [--print] </B><DD>
  62 Prints parameters, command line options and input and output filenames
  63 to stdout. The output may be used as parameters of <B>t-avg</B> for
  64 future use by re-directing stdout to <I>t-avg.par</I>.
  65 <DT><B>-v [--version] </B><DD>
  66 Prints version information on standard output, then exits successfully.
