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.

Generate alternative modified peptide forms according to ModificationsDB.
An input peptide sequence containing modifications is used as template to generate all modification-carrying residue permutations (n choose k possibilities) that are physicochemically possible according to ModificationsDB. Instead of the target sequence, the permutations are transferred to the decoy sequence that might contain additional modifiable residues. E.g. target sequence SAS(Phospho)K could result in [SAS(Phospho)K, S(Phospho)ASK] but the responding set of the decoy sequence SSS(Phospho)K would be [SSS(Phospho)K, S(Phospho)SSK].
