Structs

Feature

A detected isotope feature: a group of hills forming an isotope envelope.

Hill

A finalized chromatographic hill (elution peak for a single m/z trace).

IsolationWindow

Precursor isolation window for an MS2 spectrum (mzML coordinates).

Peak

A single centroided MS1 peak.

ScoredFeature

Feature with isotope pattern scoring applied.

Spectrum

A single mass spectrum with all its peaks.

Enums

Polarity

Ion polarity: which way the charge-carrying adduct shifts m/z, and so which way to undo it when recovering a neutral mass.

Constants

PROTON_MASS

Mass of a proton, in Da.
