PrecursorIon.Constructor

Remarks

The copy constructor copies every field, including CollisionEnergy, FragmentationMethod and IsolationSpecificity. The m/z constructor leaves those three at their defaults.

Syntax

Syntax	Description
PrecursorIon()	PrecursorIon object constructor.
PrecursorIon(PrecursorIon pi)	PrecursorIon object copy constructor.
PrecursorIon(double mz, double intensity = 0, int charge = 0, double isoMz = 0, double isoWidth = 0)	Creates a precursor from its monoisotopic m/z, with optional intensity, charge, isolation m/z, and isolation width.

Parameters

Name	Type	Description
pi	PrecursorIon	The precursor to copy.
mz	double	The monoisotopic m/z.
intensity	double	The intensity of the precursor peak.
charge	int	The charge state.
isoMz	double	The isolation m/z of the precursor selection window.
isoWidth	double	The isolation width of the precursor selection window.

Example

using Nova.Data;

PrecursorIon precursor = new PrecursorIon(652.3412, 1.2e6, 2, 652.84, 1.6);
precursor.FragmentationMethod = FragmentationType.HCD;

// The copy carries every field.
PrecursorIon copy = new PrecursorIon(precursor);
