LipidMS (version 1.0.0)

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(results, MS1, label, adductsTable = LipidMS::adductsTable,
  rttol = 10, ppm = 10)

Arguments

results

annotation results for an unlabelled sample. Output of identification functions (i.e. idPOS$results).

MS1

Data frame with at least three columns: m.z, RT, int. Peak list for the labelled sample. Output of dataProcessing function (MS$peaklist).

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.

Value

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