Detailed Description

Builds a MaxQuant msms.txt.

This class is closely related to QualityControl, it creates an msms.txt similar to a MaxQuant msms.txt. But not all columns of a MaxQuant file get exported. By the construction of an object, the column names of the msms values are added to the msms.txt. For the construction a valid path is needed (check out constructor) where the msms.txt can be stored. To fill the output msms.txt with data from the MS/MS run use the exportFeatureMap function, it needs a FeatureMap and the matching ConsensusMap as an input. To check if the created msms.txt is writable use the function isValid.

Constructor & Destructor Documentation

◆ MQMsms()

MQMsms ( const std::string & path )

explicit

Creates MQMsms object and msms.txt in given path.

If the path for the constructor is empty (path not valid), no msms.txt is created. If the creation of the fstream object is successful a constant header is added to the msms.txt If the path does not exist, it will be created

Exceptions

Exception::FileNotWritable if msms.txt could not be created

Parameters

[in] path that is the path where msms.txt has to be stored

private

Export one Feature as a row in msms.txt.

If the feature has no PepID's or the corresponding CF has no PepIDs,
no row will be exported

Parameters

[in]	f	Feature to extract evidence data
[in]	cmap	ConsensusMap to extract msms data if Feature has no valid PeptideIdentifications
[in]	c_feature_number	Index of corresponding ConsensusFeature in ConsensusMap
[in]	raw_file	is specifying the raw_file the feature belongs to
[in]	UIDs	UIDs of all PeptideIdentifications of the ConsensusMap
[in]	mp_f	Mapping between the FeatureMap and ProteinIdentifications for the UID from PeptideIdenfitication::buildUIDfromAllPepIds
[in]	exp	MS Experiment holds evidence data to extract
[in]	prot_map	Mapping a protein_accession to its description(proteinname, genename...)
