Representation of spectrum identification results and associated data.

This class provides capabilities for storing spectrum identification results from different types of experiments/molecules (proteomics: peptides/proteins, metabolomics: small molecules, "nucleomics": RNA).

The class design has the following goals:

Provide one structure for storing all relevant data for spectrum identification results.
Store data non-redundantly.
Ensure consistency (e.g. no conflicting information; no "dangling references").
Allow convenient and efficient querying.
Support different types of experiments, as mentioned above, in one common framework.

The following important subordinate classes are provided to represent different types of data:

Class	Represents	Key	Proteomics example	Corresponding legacy class
ProcessingStep	Information about a data processing step that was applied (e.g. input files, software used, parameters)	Combined information	Mascot search	ProteinIdentification
Observation	A search query (with identifier, RT, m/z) from an input file, i.e. an MS2 spectrum or feature (for accurate mass search)	File/Identifier	MS2 spectrum	PeptideIdentification
ParentSequence	An entry in a FASTA file with associated information (sequence, coverage, etc.)	Accession	Protein	ProteinHit
IdentifiedPeptide/-Oligo/-Compound	An identified molecule of the respective type	Sequence (or identifier for a compound)	Peptide	PeptideHit
ObservationMatch	A match between a query (Observation), identified molecule (Identified...), and optionally adduct	Combination of query/molecule/adduct references	Peptide-spectrum match (PSM)	PeptideIdentification/PeptideHit

To populate an IdentificationData instance with data, "register..." functions are used. These functions return "references" (implemented as iterators) that can be used to refer to stored data items and thus form connections. For example, a protein can be stored using registerParentSequence, which returns a corresponding reference. This reference can be used to build an IdentifiedPeptide object that references the protein. An identified peptide referencing a protein can only be registered if that protein has been registered already, to ensure data consistency. Given the identified peptide, information about the associated protein can be retrieved efficiently by simply dereferencing the reference.

To ensure non-redundancy, many data types have a "key" (see table above) to which a uniqueness constraint applies. This means only one item of such a type with a given key can be stored in an IdentificationData object. If items with an existing key are registered subsequently, attempts are made to merge new information (e.g. additional scores) into the existing entry. The details of this merging are handled in the merge function in each data class.

Warning: This class is not thread-safe while being modified. Remove elements from a set (or ordered multi_index_container) if they fulfill a predicate (TODO: deprecate and use std::erase_if with C++20 adoption)
