LipidMS (version 2.1.2)

searchIsotopes: Target isotopes search

Description

This function uses annotation results of an unlabelled sample to search for labelled compounds in a labelled sample.

Usage

searchIsotopes(
  msobject,
  label,
  adductsTable = LipidMS::adductsTable,
  rttol = 10,
  ppm = 10,
  coelCutoff = 0.8
)

Arguments

msobject

a msobject generated by any of the identification functions.

label

isotope employed for the experiment. It can be "13C" or "D".

adductsTable

adducts table employed for lipids annotation.

rttol

rt window in seconds.

ppm

mass error tolerance.

coelCutoff

coelution score threshold between isotopes. By default, 0.8.

Value

List with the isotopes for each compound in the results data frame.
