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.
