Welcome to hpNAFF Analysis(version 0.0.3, build 178201). ©2018 Heiko Pälike Usage: hpnaff [options] file file format: tab separated columns, data must be equidistantly spaced. Instead of file can specify '-' for stdin. -h, --help: Displays help message. -r, --fracRMSChangeLimit: fracRMSChangeLimit. Default: 0.000002 -f, --fracFreqAccuracyLimit: fracFreqAccuracyLimit. Default: 0.00000001 -m, --maxFrequencies: maxFrequencies. Default: 30 -c, --freqCycleLimit: freqCycleLimit. Default: 100 -l, --lowerFreqLimit: lowerFreqLimit. Default: 0.0 -u, --upperFreqLimit: upperFreqLimit. Default: 0.5 (NYQUIST) -d, --detrendingOrder: Order for polynomial detrending. 0 removes DC only. >0 removes a polynomial fit. Default: not set -dC, --detrendChunks: Option to apply detrending (-d) to individual chunks. Default: false -fAL, --filterAbscissaLower: filter on Abscissa (x-axis) data greater or equal than value specified. -fAU, --filterAbscissaUpper: filter on Abscissa (x-axis) data lesser or equal than value specified. -s, --chunkSize: Split the input file into chunks of this size. Default: not set, no chunking -w, --window_offsets: Specify windowing offset for evolutive analysis. Default: chunkSize if set, or None. -z, --columnSeparator: Use this as columns separtor for input file instead of default tab \t. Default: \t -k, --skipHeaderLines: Specify number of (header)lines to be skipped. Default: 0 -n, --decimate: Specify decimation of input data. Default: 1 (take every value) -a, --abscissaColumn: Specify column number for abscissa (time or depth). Default: 1 -o, --ordinateColumn: Specify column number for ordinate (data). Default: 2 -C, --complex: Compute spectra for complex input. Default: false. If true, by default takes values from abscissa column + 1. -Co, --ComplexOrdinateColumn: Specify column number for ordinate (data), complex part. Default: 3 (if C option used) -t, --deltaT: Specify time/depth offset between data. Default: 1.0 -x, --ratios: Compute and output frequency ratio matrix. Default: false. --ratio_list: If ratio_option is set, provides comma separated list of frequency ratios to highlight in output. --output_detrended_data: Output detrended data to this filename. Not implemented yet. --version: Shows current version and build of this software -v, --verbose: Print verbose messages. Specify multiple times to increase verbosity. --references: Shows references to papers and sources. --licenses: Shows licenses of code components used in this software. |
