plotAnalyteXICs {DIAlignR}R Documentation

Plot extracted-ion chromatogram.

Description

Plot extracted-ion chromatogram.

Usage

plotAnalyteXICs(analyte, run, dataPath = ".", maxFdrQuery = 1,
  XICfilter = "sgolay", SgolayFiltOrd = 4, SgolayFiltLen = 9,
  runType = "DIA_proteomics", oswMerged = TRUE,
  nameCutPattern = "(.*)(/)(.*)", analyteInGroupLabel = FALSE,
  peakAnnot = NULL, Title = NULL)

Arguments

analyte

(string) An analyte is as PRECURSOR.GROUP_LABEL or as PEPTIDE.MODIFIED_SEQUENCE and PRECURSOR.CHARGE from osw file.

run

(string) Name of a mzml file without extension.

dataPath

(char) Path to mzml and osw directory.

maxFdrQuery

(numeric) A numeric value between 0 and 1. It is used to filter features from osw file which have SCORE_MS2.QVALUE less than itself.

XICfilter

(string) This must be one of the strings "sgolay", "none".

SgolayFiltOrd

(integer) It defines the polynomial order of filer.

SgolayFiltLen

(integer) Must be an odd number. It defines the length of filter.

runType

(char) This must be one of the strings "DIA_proteomics", "DIA_Metabolomics".

oswMerged

(logical) TRUE for experiment-wide FDR and FALSE for run-specific FDR by pyprophet.

nameCutPattern

(string) regex expression to fetch mzML file name from RUN.FILENAME columns of osw files.

analyteInGroupLabel

(logical) TRUE for getting analytes as PRECURSOR.GROUP_LABEL from osw file.

peakAnnot

(numeric) Peak-apex time.

Title

(logical) TRUE: name of the list will be displayed as title.

Value

A plot to the current device.
