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: ProteinNameProtein 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_iddesignates 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: CECollision energy
Annotation free textTransition-level annotation, e.g. y7
UniprotId free text; synonyms: UniprotID A Uniprot identifier
LabelType free textoptional 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: CompoundIdShould be unique for the analyte, if present the file will be interpreted as a metabolomics file
SMILESfree textSMILES identifier of the compound
SumFormulafree textmolecular 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"
Parameters of this class are:

NameTypeDefaultRestrictionsDescription
retentionTimeInterpretation stringiRT iRT, seconds, minutesHow to interpret the provided retention time (the retention time column can either be interpreted to be in iRT, minutes or seconds)
override_group_label_check stringfalse true, falseOverride an internal check that assures that all members of the same PeptideGroupLabel have the same PeptideSequence (this ensures that only different isotopic forms of the same peptide can be grouped together in the same label group). Only turn this off if you know what you are doing.
force_invalid_mods stringfalse true, falseForce reading even if invalid modifications are encountered (OpenMS may not recognize the modification)
