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:

Document which metavalues of Protein/PeptideHit are filled when reading ProtXML (Chris)

Writing of protXML is currently not supported

Member Typedef Documentation

◆ ProteinGroup

typedef ProteinIdentification::ProteinGroup ProteinGroup

Constructor & Destructor Documentation

◆ ProtXMLFile()

Constructor.

Member Function Documentation

◆ endElement()

void endElement	(	const XMLCh * const	,

◆ 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::FileNotFound	is thrown if the file could not be opened
Exception::ParseError	is 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

mass	Modified AA's mass
origin	AA 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::UnableToCreateFile is thrown if the file could not be created
