Generic Workflow Nodes for KNIME: OpenMS version by Freie Universitaet Berlin, Universitaet Tuebingen, and the OpenMS Team

Removes noise from profile spectra by using Gaussian filter (on uniform as well as non-uniform data).

Version of the tool that generated this parameters file.
Whether to load all data and process them in-memory or whether to process the data on the fly (lowmemory) without loading the whole file into memory first
Name of log file (created only when specified)
Sets the debug level
Sets the number of threads allowed to be used by the TOPP tool
Disables progress logging to command line
Overwrite tool specific checks.
Enables the test mode (needed for internal use only)
Use a gaussian filter width which has approximately the same width as your mass peaks (FWHM in m/z).
Gaussian width, depending on the m/z position. The higher the value, the wider the peak and therefore the wider the gaussian.
If true, instead of the gaussian_width value, the ppm_tolerance is used. The gaussian is calculated in each step anew, so this is much slower.

NoiseFilterGaussian Std Output
The text sent to standard out during the execution of NoiseFilterGaussian.
NoiseFilterGaussian Error Output
The text sent to standard error during the execution of NoiseFilterGaussian. (If it appears in gray, it's the output of a previously failing run which is preserved for your trouble shooting.)
