Detecting transitions

Transitions used for detection of analyte

Detecting transitions represent the set of transitions of an assay that should be used to enable candidate peak group detection. Ideally they were observed and validated in previous experiments and have an associated library intensity.

For an overview, see Schubert OT et al., Building high-quality assay libraries for targeted analysis of SWATH MS data., Nat Protoc. 2015 Mar;10(3):426-41. doi: 10.1038/nprot.2015.015. Epub 2015 Feb 12. PMID: 25675208

void setDetectingTransition (bool val)
 
Identifying transitions

Transitions used for differentiation between different analyte isomers (peptidoforms).

Identifying transitions represent the set of transitions of an assay that should be used for the independent identification of a candidate peak group (often in relation to another analyte isomer or peptidoform). These transitions could for example be site-determining transitions in a phospho-proteomic DIA experiment. These transitions will be scored independently of the detecting transitions.

bool isIdentifyingTransition () const
 
void setIdentifyingTransition (bool val)
 
Quantifying transitions

Transitions used for quantification

Quantifying transitions represent the set of transitions of an assay that should be used for the quantification of the peptide. This includes exclusion of e.g. interfered transitions (example: light/heavy peptide pairs isolated in the same swath window), that should not be used for quantification of the peptide.

Detailed Description

This class stores a SRM/MRM transition.

This class is capable of representing a <Transition> tag in a TraML document completely and contains all associated information.

The default values for precursor m/z is 0.0 which indicates that it is uninitialized.
