program to filter data in an ASCII file

SYNOPSIS

Usage: pkfilterascii -i input.txt [-ic column]*

Options: [-f filter] [-dz value] [-t]

Advanced options: [-tapz value]* [-fwhm value]* [-srf filename]* [-win col] [-wout value]* [-interp type] [-wt type] [-wf family] [-cut threshold]

Description

The utility pkfilterascii filters the columns defined by the option -ic. A varietey of filters can be selected from with the option -f. The kernel size is defined with the option -dz. Alternatively, you can define your own filter tap values (use the option -tapz for each tap). In case of spectral filtering, define the full width half max values (-fwhm value) or spectral response functions in ASCII files (-srf filename).

Options

• use either -short or --long options (both --long=value and --long value are supported)
• short option -h shows basic options only, long option --help shows all options

  short	long	type	default	description
  i	input	std::string		input ASCII file
  o	output	std::string		Output ASCII file
  ic	inputCols	int		input columns (e.g., for three dimensional input data in first three columns use: -ic 0 -ic 1 -ic 2
  f	filter	std::string		filter function (to be implemented: dwt, dwti,dwt_cut)
  dz	dz	int		filter kernel size in z (band or spectral dimension), must be odd (example: 3).. Set dz>0 if 1-D filter must be used in band domain
  tapz	tapz	double		taps used for spectral filtering
  fwhm	fwhm	double		list of full width half to apply spectral filtering (-fwhm band1 -fwhm band2 ...)
  srf	srf	std::string		list of ASCII files containing spectral response functions (two columns: wavelength response)
  win	wavelengthIn	int		column number of input ASCII file containing wavelengths
  wout	wavelengthOut	double		list of wavelengths in output spectrum (-wout band1 -wout band2 ...)
  interp	interp	std::string	akima	type of interpolation for spectral filtering (see http://www.gnu.org/software/gsl/manual/html_node/Interpolation-Types.html)
  t	transpose	bool	false	transpose output with samples in rows and wavelengths in cols
  wt	wavelet	std::string	daubechies	wavelet type: daubechies,daubechies_centered, haar, haar_centered, bspline, bspline_centered
  wf	family	int	4	wavelet family (vanishing moment, see also http://www.gnu.org/software/gsl/manual/html_node/DWT-Initialization.html)
  cut	cut	double	0	threshold to cut dwt coefficients. Use 0 to keep all.
