TICPeakFinder
Class: maltcms.commands.fragments.peakfinding.TICPeakFinder
Workflow Slot: PEAKFINDING
Description: Finds peaks based on total ion current (TIC), using a simple extremum search within a window, combined with a signal-to-noise parameter to select peaks.
Variables
Required

Provided
var.tic_peaks var.tic_filtered var.peak_name var.peak_retention_time var.peak_start_time var.peak_end_time var.peak_area var.baseline_start_time var.baseline_stop_time var.baseline_start_value var.baseline_stop_value
Configurable Properties
Name: baselineEstimator
Default Value: LoessMinimaBaselineEstimator(bandwidth=0.3, accuracy=1.0E-12, robustnessIterations=2, minimaWindow=100)
Description:
The baseline estimator to use.
Name: filter
Default Value: [MultiplicationFilter(factor=1.0)]
Description:
The filters to use for smoothing and filtering of the tic.
Name: integratePeaks
Default Value: false
Description:
If true, peak areas will be integrated.
Name: integrateRawTic
Default Value: true
Description:
If true, the raw tic will be used for integration. If false, the smoothed and filtered tic will be used.
Name: integrateTICPeaks
Default Value: true
Description:
If true, the tic will be used to integrate peaks.
Name: peakNormalizers
Default Value: []
Description:
A list of peak normalizers. Each normalizer is invoked and its result multiplied to the intermediate result with the original peak’s area.
Name: peakSeparationWindow
Default Value: 10
Description:
The minimum number of scans between two peak apices.The second peak will be omitted, if it is closer to the first peak than allowed by the parameter.
Name: peakThreshold
Default Value: 0.01
Description:
The minimal local signal-to-noise threshold required for a peak to be reported.
Name: removeOverlappingPeaks
Default Value: true
Description:
The removal of overlapping peaks is currently unavailable.
Name: saveGraphics
Default Value: false
Description:
If true, a plot of the local estimated signal-to-noise and of peak locations will be created.
Name: snrWindow
Default Value: 50
Description:
Width of the sliding window for local snr estimation.
Name: subtractBaseline
Default Value: false
Description:
If true, the estimated baseline is subtracted from the smoothed and filtered tic.
Name: ticFilteredVarName
Default Value: tic_filtered
Description:
Name: ticPeakVarName
Default Value: tic_peaks
