Search for peptide pairs linked with a labeled cross-linker

This tool performs a search for cross-links in the given mass spectra. It uses linked MS1 features to pair up MS2 spectra and uses these pairs to find the fragment peaks that contain the linker and those that do not.

It executes the following steps in order:

Reading of MS2 spectra from the given mzML file
Processing of spectra: deisotoping and filtering
Digesting and preprocessing the protein database, building a peptide pair index dependent on the precursor masses of the MS2 spectra
Generating theoretical spectra of cross-linked peptides and aligning the experimental spectra against those
Scoring of cross-link spectrum matches
Using PeptideIndexer to map the peptides to all possible source proteins
Writing out the results in idXML, mzid according to mzIdentML 1.2 specifications and/or in the xQuest output format

See below or have a look at the INI file (via "OpenPepXL -write_ini myini.ini") for available parameters and more functionality.

Input: MS2 spectra, linked features from FeatureFinderMultiplex and fasta database of proteins expected to be cross-linked in the sample

The spectra should be provided as one mzML file. If you have multiple files, e.g. for multiple fractions, you should run this tool on each file separately. The database can either be provided as one merged file containing targets and decoys or as two separate files. A consensusXML file, that links the MS1 feature pairs from heavy and light cross-linkers is also required. This file can be generated by the tool FeatureFinderMultiplex. Setting up FeatureFinderMultiplex: In the FeatureFinderMultiplex parameters you have to change the mass of one of the labels to the difference between the light and heavy (e.g. change the mass of Arg6 to 12.075321 for labeled DSS) in the advanced options. The parameter -labels should have one empty label ( [] ) and the label you adapted (e.g. [][Arg6]). For the other settings refer to the documentation of FeatureFinderMultiplex.

Parameters

The parameters for fixed and variable modifications refer to additional modifications beside the cross-linker. The linker used in the experiment has to be described using the cross-linker specific parameters. Only one mass is allowed for a cross-linker, that links two peptides (-cross_linker:mass_light), while multiple masses are possible for mono-links of the same cross-linking reagent. Mono-links are cross-linkers, that are linked to one peptide by one of their two reactive groups. The masses refer to the light version of the linker. The parameter -cross_linker:mass_iso_shift defines the difference between the light and heavy versions of the cross-linker and the mono-links. The parameters -cross_linker:residue1 and -cross_linker:residue2 are used to enumerate the amino acids, that each end of the linker can react with. This way any heterobifunctional cross-linker can be defined. To define a homobifunctional cross-linker, these two parameters should have the same value. The parameter -cross_linker:name is used to solve ambiguities arising from different cross-linkers having the same mass after the linking reaction (see section on output for clarification).

Output: XL-MS Identifications with scores and linked positions in the proteins

There are three file formats for output of data possible. idXML is the internal format of OpenMS, and is recommended for post-processing using other TOPP tools like XFDR or TOPPView. The second format xquest.xml is the output format of xQuest, which is a popular XL-MS ID tool. This format is compatible with a number of post-processing and visulization tools, like xProphet for FDR estimation (Leitner, A. et al., 2014, Nature protocols) and through the xQuest Results Viewer also the XlinkAnalyzer for visualization and analysis using protein structures (Kosinski, J. et al., 2015, Journal of structural biology). The third format is mzIdentML according to the specifications for XL-MS ID data in version 1.2 (Vizcaíno, J. A. et al., 2017, Mol Cell Proteomics). This is a standardized long term storage format and compatible with complete submissions to the PRIDE database, that is part of the ProteomeXchange consortium. The specification includes the XLMOD database of cross-linking reagents, and if the provided cross-link mass matches one from the database, its accession and name are used. If the name is provided with the -cross_linker:name parameter, it is used to solve ambiguities arising from different cross-linkers having the same mass after the linking reaction (e.g. DSS and BS3). It is also used as the name of the linker, if no matching masses are found in the database.
