NAME

       pkfilterascii - program to filter data in an ASCII file

SYNOPSIS

       pkfilterascii -i input [-ic column] [options] [advanced options]

DESCRIPTION

       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

       -i filename, --input filename
              input ASCII file

       -o filename, --output filename
              Output ASCII file

       -ic column, --inputCols column
              input columns (e.g., for three dimensional input data in first three columns use: -ic 0 -ic 1  -ic
              2)

       -f filter, --filter filter
              filter function (to be implemented: dwt, dwti,dwt_cut)

       -dz value, --dz value
              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

       -t, --transpose
              transpose output with samples in rows and wavelengths in cols

       -v level, --verbose level
              verbose

       Advanced options

       -tapz value, --tapz value
              taps used for spectral filtering

       -fwhm value, --fwhm value
              list of full width half to apply spectral filtering (-fwhm band1 -fwhm band2 ...)

       -srf filename, --srf filename
              list of ASCII files containing spectral response functions (two columns: wavelength response)

       -win col, --wavelengthIn col
              column number of input ASCII file containing wavelengths

       -wout value, --wavelengthOut value
              list of wavelengths in output spectrum (-wout band1 -wout band2 ...)

       -interp type, --interp type
              type         of         interpolation         for         spectral         filtering          (see
              http://www.gnu.org/software/gsl/manual/html_node/Interpolation-Types.html)

       -wt type, --wavelet type
              wavelet type: daubechies,daubechies_centered, haar, haar_centered, bspline, bspline_centered

       -wf family, --wf family
              wavelet  family  (vanishing moment, see also http://www.gnu.org/software/gsl/manual/html_node/DWT-
              Initialization.html)

       -cut threshold, --cut threshold
              threshold to cut dwt coefficients.  Use 0 to keep all.
