Search for cross-linked peptide pairs in tandem MS spectra

This tool performs a search for cross-links in the given mass spectra.

It executes the following steps in order:

Reading of MS2 spectra from the given mzML file, MS1 spectra are ignored for now
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 "OpenPepXLLF -write_ini myini.ini") for available parameters and more functionality.

Input: MS2 spectra 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.

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, 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. To search for isotopically labeled pairs of cross-linkers see the tool OpenPepXL. 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 caused by different cross-linkers with 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 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 format and will be compatible with complete submissions to the PRIDE database, which 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.

residue1[K, N-term] Comma separated residues, that the first side of a bifunctional cross-linker can attach to

residue2[K, N-term] Comma separated residues, that the second side of a bifunctional cross-linker can attach to

nameDSS Name of the searched cross-link, used to resolve ambiguity of equal masses (e.g. DSS or BS3)

+++algorithmAdditional algorithm settings

number_top_hits5 Number of top hits reported for each spectrum pair

deisotopeauto Set to true, if the input spectra should be deisotoped before any other processing steps. If set to auto the spectra will be deisotoped, if the fragment mass tolerance is < 0.1 Da or < 100 ppm (0.1 Da at a mass of 1000)true,false,auto

use_sequence_tagsfalse Use sequence tags (de novo sequencing of short fragments) to filter out candidates before scoring. This will make the search faster, but can impact the sensitivity positively or negatively, depending on the dataset.true,false

sequence_tag_min_length2 Minimal length of sequence tags to use for filtering candidates. Longer tags will make the search faster but much less sensitive. Ignored if 'algorithm:use_sequence_tags' is false.
