Allows the searching of neighboring isotope peak masses for poorly resolve precursors. Up to two alternative isotope peak masses will be searched in addition to the presumed precursor peak mass to correct for errors in monoisotopic precursor peak identification.
- 0 = Off
- 1 = first isotope peak offset
- 2 = both first and second isotope peak offsets
- 3 = first, second, and third isotope peak offsets
1.0.0 - present
To search presumed monoisotopic precursor mass and one additional isotope peak mass:
isotope_error = 1
