Detailed Description

Used to load (storing not supported, yet) ProtXML files.

This class is used to load (storing not supported, yet) documents that implement the schema of ProtXML files.

A documented schema for this format comes with the TPP and can also be found at https://github.com/OpenMS/OpenMS/tree/develop/share/OpenMS/SCHEMAS

OpenMS can only read parts of the protein_summary subtree to extract protein-peptide associations. All other parts are silently ignored.

For protein groups, only the "group leader" (which is annotated with a probability and coverage) receives these attributes. All indistinguishable proteins of the same group only have an accession and score of -1.

Note
This format will eventually be replaced by the HUPO-PSI (mzIdentML and mzQuantML) formats.
Todo:

Docu in base class.

◆ load()

void load ( const String filename,
ProteinIdentification protein_ids,
PeptideIdentification peptide_ids

Loads the identifications of an ProtXML file without identifier.

The information is read in and the information is stored in the corresponding variables

Exceptions
Exception::FileNotFoundis thrown if the file could not be opened
Exception::ParseErroris thrown if an error occurs during parsing

◆ matchModification_()

void matchModification_ ( const double  mass,
const String origin,
String modification_description 
)
protected

find modification name given a modified AA mass

Matches a mass of a modified AA to a mod in our modification db For ambiguous mods, the first (arbitrary) is returned If no mod is found an error is issued and the return string is empty

Note
A duplicate of this function is also used in PepXMLFile
Parameters
massModified AA's mass
originAA one letter code
modification_description[out] Name of the modification, e.g. 'Carboxymethyl (C)'

◆ registerProtein_()

void registerProtein_ ( const String protein_name)
protected

Creates a new protein entry (if not already present) and appends it to the current group.

◆ resetMembers_()

void resetMembers_ ( )
protected

reset members after reading/writing

◆ startElement()

void startElement ( const XMLCh * const  ,
const XMLCh * const  ,
const XMLCh *const  qname,
const xercesc::Attributes &  attributes 
)
overrideprotected

Docu in base class.

◆ store()

void store ( const String filename,
const ProteinIdentification protein_ids,
const PeptideIdentification peptide_ids,
const String document_id = "" 
)

[not implemented yet!] Stores the data in an ProtXML file

[not implemented yet!] The data is stored in the file 'filename'.

Exceptions
Exception::UnableToCreateFileis thrown if the file could not be created
