Detailed Description

Used to load and store PepXML files.

This class is used to load and store documents that implement the schema of PepXML 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

◆ keepNativeSpectrumName()

void keepNativeSpectrumName ( bool keep )

inline

Whether we should keep the native spectrum name of the pepXML.

Note: This will lead to a "pepxml_spectrum_name" meta value being added to each PeptideIdentification containing the original name of the spectrum in TPP format.

Loads peptide sequences with modifications out of a PepXML file.

Parameters

filename	PepXML file to load
proteins	Protein identification output
peptides	Peptide identification output
experiment_name	Experiment file name, which is used to extract the corresponding search results from the PepXML file.
