FSA_spectra_marker_generator: FSA Spectra Marker Generator

In IDSL.FSA: Fragmentation Spectra Analysis (FSA)

FSA Spectra Marker Generator

Description

This function generates spectra markers

Usage

FSA_spectra_marker_generator(FSdb, ratio2basePeak4nSpectraMarkers = 0,
aggregationLevel = NA)

Arguments

FSdb	FSdb object from the 'msp2FSdb' module
ratio2basePeak4nSpectraMarkers	Ratio of peaks in fragmentation spectra to the basepeak to calculate minimum qualified number of matched abundant peaks
aggregationLevel	c(NA, 0, 1, 2, 3). When 'NA', this function returns a matrix for the spectra markers. When integer numbers are used, the ion marker masses are grouped by a rounding digit equal to this number.

Value

spectraMarkerMass	a grouped or a matrix of ion marker masses corresponding to FSdb ids
nSpectraMarkers	number of spectra markers for each FSdb id
