Detailed Description

Generate assays from a TargetedExperiment.

Will generate assays from a raw, unfiltered TargetedExperiment, as can be generated by TargetedFileConverter.

Transitions can be selected according to a set of rules, as described in Schubert et al., 2015 (PMID 25675208).

In addition, unique ion signature (UIS) (Sherman et al., 2009; PMID 19556279) transitions can be generated based on empirically observed or in silico generated ion series. This is described in detail in the IPF paper (Rosenberger et al. 2017; PMID 28604659).

◆ generateTheoreticalPeptidoforms_()

Generate alternative modified peptide forms according to ModificationsDB.

Performs the following actions:

Step 1: For each peptide, compute all theoretical alternative peptidoforms; see transitions generateTargetInSilicoMap_()
Step 2: Generate target identification transitions; see generateTargetAssays_()
Step 3a: Generate decoy sequences that share peptidoform properties with targets; see generateDecoySequences_()
Step 3b: Generate decoy in silico peptide map containing theoretical transition; see generateDecoyInSilicoMap_()
Step 4: Generate decoy identification transitions; see generateDecoyAssays_()

The IPF algorithm uses the concept of "identification transitions" that are used to discriminate different peptidoforms, these are generated in this function. In brief, the algorithm takes the existing set of peptides and transitions and then appends these "identification transitions" for targets and decoys. The novel transitions are set to be non-detecting and non-quantifying and are annotated with the set of peptidoforms to which they map.

fragment_types	the fragment types to consider for annotation
fragment_charges	the fragment charges to consider for annotation

enable_ms2_precursors	whether MS2 precursors should be considered
mz_threshold	the product m/z threshold in Th for annotation
swathes	the swath window settings (to exclude fragment ions falling
round_decPow	round product m/z values to decimal power (default: -4)
max_num_alternative_localizations	maximum number of allowed peptide sequence permutations
shuffle_seed	set seed for shuffle (-1: select seed based on time)
