pkfilterascii1

Usage

Overview

pkfilterascii filters the columns defined by the option FC-icF[0]. A varietey of filters can be selected from with the option FC-fF[0]. The kernel size is defined with the option FC-dzF[0]. Alternatively, you can define your own filter tap values (use the option FC-tapzF[0] for each tap). In case of spectral filtering, define the full width half max values (FC-fwhmF[0] value) or spectral response functions in ASCII files (FC-srfF[0] filename).

Options

FC-iF[0] filename, FC--inputF[0] filename

input ASCII file

FC-oF[0] filename, FC--outputF[0] filename

Output ASCII file

FC-icF[0] column, FC--inputColsF[0] column

input columns (e.g., for three dimensional input data in first three columns use: FC-icF[0] 0 FC-icF[0] 1 FC-icF[0] 2)

FC-fF[0] filter, FC--filterF[0] filter

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

FC-dzF[0] value, FC--dzF[0] 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

FC-tF[0], FC--transposeF[0]

transpose output with samples in rows and wavelengths in cols

FC-vF[0] level, FC--verboseF[0] level

verbose

list of full width half to apply spectral filtering (FC-fwhmF[0] band1 FC-fwhmF[0] band2 ...)

FC-srfF[0] filename, FC--srfF[0] filename

FC-interpF[0] type, FC--interpF[0] type

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

FC-wtF[0] type, FC--waveletF[0] type

FC-cutF[0] threshold, FC--cutF[0] threshold

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