Method Details

getRecalibratedPrecursor

public static Precursor getRecalibratedPrecursor(Precursor precursor,
 double mzCorrection,
 double rtCorrection)

Returns a recalibrated precursor.

Parameters:

precursor - The precursor to recalibrate.

mzCorrection - The m/z correction to apply.

rtCorrection - The retention time correction to apply.

Returns:

A new precursor with recalibrated mz and rt.

getRecalibratedMz

public static double[] getRecalibratedMz(TreeMap<Double,Double> mzCorrections,
 double[] originalMz)

Returns a recalibrated peak list.

Parameters:

mzCorrections - The corrections to apply.

originalMz - The original m/z array.

Returns:

A new array of recalibrated m/z.
