	)		const

Score identification transitions against detection transitions of a single peakgroup in a chromatogram using only chromatographic properties.

This function only uses the chromatographic properties (coelution, signal to noise, etc.) of a peakgroup in a chromatogram to compute scores. The scores are computed by scoring identification against detection transitions.

The scores are returned in the OpenSwath_Scores object. Only those scores specified in the OpenSwath_Scores_Usage object are computed.

Parameters

Score a single peakgroup in a chromatogram using only chromatographic properties.
