MS-GF+ must be installed before this wrapper can be used. Please make sure that Java and MS-GF+ are working.
At the time of writing, MS-GF+ can be downloaded from https://github.com/MSGFPlus/msgfplus/releases.
The following MS-GF+ version is required: MS-GF+ 2019/07/03. Older versions will not work properly, giving an error: [Error] Invalid parameter: -maxMissedCleavages.
Input spectra for MS-GF+ have to be centroided; profile spectra will raise an error in the adapter.
The first time MS-GF+ is applied to a database (FASTA file), it will index the file contents and generate a number of auxiliary files in the same directory as the database (e.g. for "db.fasta": "db.canno", "db.cnlap", "db.csarr" and "db.cseq" will be generated). It is advisable to keep these files for future MS-GF+ searches, to save the indexing step.
This adapter supports relative database filenames, which (when not found in the current working directory) are looked up in the directories specified by 'OpenMS.ini:id_db_dir'.
The adapter works in three steps to generate an idXML file: First MS-GF+ is run on the input MS data and the sequence database, producing an mzIdentML (.mzid) output file containing the search results. This file is then converted to a text file (.tsv) using MS-GF+' "MzIDToTsv" tool. Finally, the .tsv file is parsed and a result in idXML format is generated.
An optional MSGF+ configuration file can be added via '-conf' parameter. See https://github.com/MSGFPlus/msgfplus/blob/master/docs/examples/MSGFPlus_Params.txt for an example and consult the MSGF+ documentation for further details. Parameters specified in the configuration file are ignored by MS-GF+ if they are also specified on the command line. This adapter passes all flags which you can set on the command line, so use the configuration file only for parameters which are not available here (this includes fixed/variable modifications, which are passed on the commandline via -mod <file>
). Thus, be very careful that your settings in '-conf' actually take effect (try running again without '-conf' file and test if the results change).
The command line parameters of this tool are:

OpenMS 3 enables reproducible analysis of large-scale mass spectrometry data. Nat Methods (2024). doi:10.1038/s41592-024-02197-7. Usage: MSGFPlusAdapter <options> Options (mandatory options marked with '*'): -in <file>* Input file (MS-GF+ parameter '-s') (valid formats: 'mzML', 'mzXML', 'mgf', 'ms2') -out <file> Output file (valid formats: 'idXML') -mzid_out <file> Alternative output file (MS-GF+ parameter '-o') Either 'out' or 'mzid_out' are required. They can be used together. (valid formats: 'mzid') -executable <file>* The MSGFPlus Java archive file. Provide a full or relative path, or make sure it can be found in your PATH environment. -database <file>* Protein sequence database (FASTA file; MS-GF+ parameter '-d'). Non-existing relative filenames are looked up via 'OpenMS.ini:id_db_dir'. (valid formats: 'FASTA') -precursor_mass_tolerance <value> Precursor monoisotopic mass tolerance (MS-GF+ parameter '-t') (default: '10.0') -precursor_error_units <choice> Unit of precursor mass tolerance (MS-GF+ parameter '-t') (default: 'ppm') (valid: 'Da', 'ppm') -isotope_error_range <range> Range of allowed isotope peak errors (MS-GF+ parameter '-ti'). Takes into account the error introduced by choosing a non-monoisotopic peak for fragmentation. Combined with 'precursor_mass_tolerance'/'precursor_error_units', this determines the actual precursor mass tolerance. E.g. for experimental mass 'exp' and calculated mass 'calc', '-precursor_mass_tolerance 20 -precursor_error_units ppm -isotope_error_range -1,2' tests '|exp - calc - n * 1.00335 Da| < 20 ppm' for n = -1, 0, 1, 2. (default: '0,1') -fragment_method <choice> Fragmentation method ('from_spectrum' relies on spectrum meta data and uses CID as fallback option; MS-GF+ parameter '-m') (default: 'from_spectrum') (valid: 'from_spectrum', 'CID', 'ETD', 'HCD') -instrument <choice> Instrument that generated the data ('low_res'/'high_res' refer to LCQ and LTQ instruments; MS-GF+ parameter '-inst') (default: 'low_res') (valid: 'low_res', 'high_res', 'TOF', 'Q_Exactive') -enzyme <choice> Enzyme used for digestion, or type of cleavage. Note: MS-GF+ does not support blocking rules. (MS-GF+ parameter '-e') (default: 'Trypsin/P') (valid: 'Alpha-lytic protease', 'Arg-C/P', 'Asp-N/B', 'Chymotrypsin/P', 'Lys-C/P', 'Lys-N', 'Trypsin/P', 'glutamyl endopeptidase', 'no cleavage', 'unspecific cleavage') -protocol <choice> Labeling or enrichment protocol used, if any (MS-GF+ parameter '-p') (default: 'automatic') (valid: 'automatic', 'phospho', 'iTRAQ', 'iTRAQ_phospho', 'TMT', 'none') -tryptic <choice> Level of cleavage specificity required (MS-GF+ parameter '-ntt') (default: 'fully') (valid: 'non', 'semi', 'fully') -min_precursor_charge <num> Minimum precursor ion charge (only used for spectra without charge information; MS-GF+ parameter '-minCharge') (default: '2') (min: '1') -max_precursor_charge <num> Maximum precursor ion charge (only used for spectra without charge information; MS-GF+ parameter '-maxCharge') (default: '3') (min: '1') -min_peptide_length <num> Minimum peptide length to consider (MS-GF+ parameter '-minLength') (default: '6') (min: '1') -max_peptide_length <num> Maximum peptide length to consider (MS-GF+ parameter '-maxLength') (default: '40') (min: '1') -matches_per_spec <num> Number of matches per spectrum to be reported (MS-GF+ parameter '-n') (default: '1') (min: '1') -min_peaks <num> Minimum number of ions a spectrum must have to be examined (default: '10') (min: '10') -add_features <true/false> Output additional features (MS-GF+ parameter '-addFeatures'). This is required by Percolator and hence by default enabled. (default: 'true') (valid: 'true', 'false') -max_mods <num> Maximum number of modifications per peptide. If this value is large, the search may take very long. (default: '2') (min: '0') -max_missed_cleavages <num> Maximum number of missed cleavages allowed for a peptide to be considered for scoring. (default: -1 meaning unlimited) (default: '-1') (min: '-1') -tasks <num> (Override the number of tasks to use on the threads; Default: (internally calculated based on inputs)) More tasks than threads will reduce the memory requirements of the search, but will be slower (how much depends on the inputs). 1 <= tasks <= numThreads: will create one task per thread, which is the original behavior. tasks = 0: use default calculation - minimum of: (threads*3) and (numSpectra/250). tasks < 0: multiply number of threads by abs(tasks) to determine number of tasks (i.e., -2 means "2 * numThreads" tasks). One task per thread will use the most memory, but will usually finish the fastest. 2-3 tasks per thread will use comparably less memory, but may cause the search to take 1.5 to 2 times as long. (default: '0') -fixed_modifications <mods> Fixed modifications, specified using Unimod (www.unimod.org) terms, e.g. 'Carbamidomethyl (C)' or 'Oxidation (M)' (default: '[Carbamidomethyl (C)]') (valid:
