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.
