peakIdQuant_newMethod: Adduct Peak quant

Description Usage Arguments Value

Description

peak must be at least 50 percent resolved from overlapping peaks. i.e. the peaks trough must be at least 50 percent of the peak apex intensity for the peak to be considered sufficiently resolved.

Arguments

mzTmp

expected mass to charge of target

rtTmp

expected retention time (in minutes) of target

peakRangeRtSub

matrix MS1 scans covering entire chromatographic range within which to identify peaks of interest. Contains the following three columns column 1 = mass, column 2 = intensity, column 3 = retention time, column 4 = scan number.

rtDevModel

loess retention time deviation model for the file.

isoPat

named numeric containing the expected mass differences between isotopes for the peptide of interest.

isoPatPred

matrix output from the IsotopicDistribution function with additional 'id' column.

minSimScore

numeric minimum dot product score for consideration (must be between 0-1, default = 0.96).

maxPpm

numeric ppm value for EIC extraction and integration.

gaussAlpha

numeric alpha value for smth.gaussian of smoother package. If supplied gaussian smoothing will be performed (suggested value = 16).

spikeScans

numeric number of scans that constitute a spike.

minPeakHeight

numeric minimum peak height, default 5000

maxRtDrift

numeric maximum retention time drift, default 20 secs

showPlots

boolean for whether plots should be produced

isoWindow

numeric isowindow size, default 10

maxGapMs1Scan

maximum MS1 scan gap, default 5

intMaxPeak

boolean integrate maximum peak
