Detailed Description

This class supports reading and writing of OpenSWATH transition lists.

The transition lists can be either comma- or tab-separated plain text files (CSV or TSV format). Modifications should be provided in UniMod format¹, but can also be provided in TPP format. For another file format that stores transitions, see also TransitionPQPFile.

The following columns are required:

PrecursorMz*	float	This describes the precursor ion m/z
ProductMz*	float; synonyms: FragmentMz	This specifies the product ion m/z
LibraryIntensity*	float; synonyms: RelativeFragmentIntensity	This specifies the relative intensity of the fragment ion
NormalizedRetentionTime*	float; synonyms: RetentionTime, Tr_recalibrated, iRT, RetentionTimeCalculatorScore	This specifies the expected retention time (normalized retention time)

For targeted proteomics files, the following additional columns should be provided:

GeneName**	free text;	Gene name (unique gene identifier)
ProteinId**	free text; synonyms: ProteinName	Protein identifier
PeptideSequence**	free text	sequence only (no modifications); synonyms: Sequence, StrippedSequence
ModifiedPeptideSequence**	free text	should contain modifications¹; synonyms: FullUniModPeptideName, FullPeptideName, ModifiedSequence
PrecursorCharge**	integer; synonyms: Charge	contains the charge of the precursor ion
ProductCharge**	integer; synonyms: FragmentCharge	contains the fragment charge
FragmentType	free text	contains the type of the fragment, e.g. "b" or "y"
FragmentSeriesNumber	integer; synonyms: FragmentNumber	e.g. for y7 use "7" here

OpenSWATH uses grouped transitions to detect candidate analyte signals. These groups are by default generated based on the input, but can also be manually specified:

TransitionGroupId**	free text; synomys: TransitionGroupName, transition_group_id	designates the transition group [e.g. peptide] to which this transition belongs
TransitionId**	free text; synonyms: TransitionName, transition_name	needs to be unique for each transition [in this file]
Decoy	1: decoy, 0: target; synomys: decoy, IsDecoy	determines whether the transition is a decoy transition or not
PeptideGroupLabel	free text	designates to which peptide label group (as defined in MS:1000893) the peptide belongs to²
DetectingTransition	0 or 1; synonyms: detecting_transition	1: use transition to detect peak group, 0: don't use transition for detection
IdentifyingTransition	0 or 1; synonyms: identifying_transition	1: use transition for peptidoform inference in the IPF Workflow, 0: don't use transition for identification
QuantifyingTransition	0 or 1; synonyms: quantifying_transition	1: use transition to quantify peak group, 0: don't use transition for quantification

Optionally, the following columns can be specified but they are not actively used by OpenSWATH:

CollisionEnergy	float; synonyms: CE	Collision energy
Annotation	free text	Transition-level annotation, e.g. y7
UniprotId	free text; synonyms: UniprotID	A Uniprot identifier
LabelType	free text	optional description of which label was used, e.g. heavy or light

For targeted metabolomics files, the following fields are also supported:

CompoundName**	free text; synonyms: CompoundId	Should be unique for the analyte, if present the file will be interpreted as a metabolomics file
SMILES	free text	SMILES identifier of the compound
SumFormula	free text	molecular formula of the compound (e.g. H2O)

Fields indicated with * are strictly required to create a TraML file. Fields indicated with ** are recommended, but only required for a specific application (such as using the transition list for an analysis tool such as OpenSwathWorkflow) or in a specific context (proteomics or metabolomics).

Remarks:

1. modifications should be supplied inside the sequence using UniMod identifiers or freetext identifiers that are understood by OpenMS. See also OpenMS::AASequence for more information. For example:
- PEPT(Phosphorylation)IDE(UniMod:27)A )
2. peptide label groups designate groups of peptides that are isotopically modified forms of the same peptide species. For example, the heavy and light forms of the same peptide will both be assigned the same peptide group label. For example:
- PEPTIDEAK -> gets label "PEPTIDEAK_gr1"
- PEPTIDEAK[+8] -> gets label "PEPTIDEAK_gr1"
- PEPT(Phosphorylation)IDEAK -> gets label "PEPTIDEAK_gr2"
- PEPT(Phosphorylation)IDEAK[+8] -> gets label "PEPTIDEAK_gr2"
