searchIsotopesmsbatch(
  msbatch,
  label,
  adductsTable = LipidMS::adductsTable,
  ppm = 10,
  coelCutoff = 0.7
)

Arguments

msbatch

annotated msbatch.

label

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

adductsTable

adducts table employed for lipids annotation.

ppm

mass error tolerance.

coelCutoff

coelution score threshold between isotopes. By default, 0.7.

Value

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