Options

version: Version of the tool that generated this parameters file.
type: Isobaric Quantitation method used in the experiment.
log: Name of log file (created only when specified)
debug: Sets the debug level
threads: Sets the number of threads allowed to be used by the TOPP tool
no_progress: Disables progress logging to command line
force: Overrides tool-specific checks
test: Enables the test mode (needed for internal use only)
select_activation: Operate only on MSn scans where any of its precursors features a certain activation method. Setting to "auto" uses HCD and HCID spectra. Set to empty string if you want to disable filtering.
reporter_mass_shift: Allowed shift (left to right) in Th from the expected position.
min_precursor_intensity: Minimum intensity of the precursor to be extracted. MS/MS scans having a precursor with a lower intensity will not be considered for quantitation.
keep_unannotated_precursor: Flag if precursor with missing intensity value or missing precursor spectrum should be included or not.
min_reporter_intensity: Minimum intensity of the individual reporter ions to be extracted.
discard_low_intensity_quantifications: Remove all reporter intensities if a single reporter is below the threshold given in 'min_reporter_intensity'.
min_precursor_purity: Minimum fraction of the total intensity in the isolation window of the precursor spectrum attributable to the selected precursor.
precursor_isotope_deviation: Maximum allowed deviation (in ppm) between theoretical and observed isotopic peaks of the precursor peak in the isolation window to be counted as part of the precursor.
purity_interpolation: If set to true the algorithm will try to compute the purity as a time weighted linear combination of the precursor scan and the following scan. If set to false, only the precursor scan will be used.
