Isotopoluage extraction parameter setup

Description

Isotopoluage extraction parameter setup

Usage

ExtractParam(
  d.extract = "extract",
  range.extract = c("all", "roi", "rtrange"),
  method.align = c("apex", "eic"),
  method.best = c("maxint", "maxcor"),
  method.quant = c("rawinroi", "raw", "baseline"),
  nscan.quant = 3,
  minfrac = 0.5,
  adj.unlabel = NULL,
  adj.label = NULL,
  adj.contaminate = FALSE,
  thr.contaminate = 0.02
)

Arguments

d.extract

directory of samples to be extracted

range.extract

EIC extraction range

  • [] 'all' - extract the entire eic

  • [] 'roi' - extract the rois related to rt range of target peaks

  • []'rtrange' - extract the eic at the range of rt range of target peaks

method.align

method for creating representative peak profile

  • [] 'apex' align with the apex of the most similar peaks

  • [] 'eic' align with the correlation of the eics from unlabelled and labelled samples

method.best

method for finding best correlated peak groups for extracted isotopoluage to determine the rt range of extracted peaks/eics

  • [] 'maxint' select the highest peak as rt range reference

  • [] 'maxcor select the most similar peak to representive peak as rt range reference

@param method.quant method for quantifying extracted isotopic peaks.

  • [] 'rawinroi' sum with raw intensities of significant scans (in ROI)

  • [] 'baseline' baseline substraxted rawinroi method

  • [] 'raw' sum with raw intensities anyway

nscan.quant

number of scans to sum up for quantifying

minfrac

minimal fraction threshold to determine the isotopic peak existed or not in the sample groups

adj.unlabel

character vector, group names of unlabelled samples for adjusting the isotopoluage of labelled samples

adj.label

character vector, group names of labelled samples to be adjusted using the unlabelled samples (pairwised with the sample groups in adj.unlabel)

adj.contaminate

logical: if adjust the contaminate using unlabelled samples, if TRUE, adj.unlabel and adj.label must be set

Value

an ExtractParam object
