Properties

Optional from

from?: number

First X value for the peak picking (default: first X value

Optional maxCriteria

maxCriteria?: boolean

Peaks are local maxima (true) or minima (false)

Default

true

Optional minMaxRatio

minMaxRatio?: number

Minimal height of small peaks based on the ratio between min and max

Default

0.00025

Optional minPeakWidth

minPeakWidth?: number

Minimal peak width

Optional noiseLevel

noiseLevel?: number

Peak under the noiseLevel (or over in case of maxCriteria=false) are ignored.

Optional normalizationOptions

normalizationOptions?: NormalizedSpectrumOptions

Normalization can be applied before peak picking. This is useful for example to correct baseline while still have a minMaxRatio filter

Optional realTopDetection

realTopDetection?: boolean

Use a quadratic optimizations with the peak and its 3 closest neighbors

Default

false

Optional sgOptions

sgOptions?: SGGOptions

Options for the Savitzky-Golay generalised algorithm. This algorithm is used to calculate the first ans second derivative. It is also used when smoothY:true to smooth the spectrum for peak picking. The Y values in case of smoothY is true will therefore be lower.

Default

{windowSize:9,polynomial:3}

Optional shape

shape?: Shape1D

Optional smoothY

smoothY?: boolean

Select the peak intensities from a smoothed version of the independent variables

Default

false

Optional to

to?: number

Last X value for the peak picking (default: last X value

Optional xVariable

xVariable?: OneLowerCase

x variable label, by default 'x'

Optional yVariable

yVariable?: OneLowerCase

y variable label, by default 'y'
