Identifies peptides in MS/MS spectra.
Legend:
required parameter
advanced parameter
This section lists all parameters supported by the tool. Parameters are organized into hierarchical subsections that group related settings together. Subsections may contain further subsections or individual parameters.
Each parameter entry contains the following information:
- Name The identifier used in configuration files and on the command line.
- Default value The value used if the parameter is not explicitly specified.
- Description A short explanation describing the purpose and behavior of the parameter.
- Tags Additional metadata associated with the parameter.
- Restrictions Allowed value ranges for numeric parameters or valid options for string parameters.
Parameter tags provide additional information about how a parameter is used. Some tags indicate whether a parameter is required or intended for advanced configuration, while others may be used internally by OpenMS or workflow tools.
Parameters highlighted as required must be specified for the tool to run successfully. Parameters marked as advanced allow fine-tuning of algorithm behavior and are typically not needed for standard workflows.
+ProSEAnnotates bottom-up MS/MS spectra using ProSE.

++1Instance '1' section for 'ProSE'
in[]
Input spectrum file(s). Multiple files are searched against the same database; the fragment index is built once and reused.input file*.mzML, *.d
database
Input protein sequence database in FASTA format.input file*.fasta
out_idxml[]
Output idXML identification file(s). Must have the same number of entries as -in.output file*.idXML
out_qpx
Output directory for QPX exchange format Parquet files. Writes per-input .psm.parquet and .pg.parquet, plus merged quantms.psm.parquet and quantms.pg.parquet.output dir
out_parquet
Output directory for OpenMS internal format Parquet files. Writes per-input .psm/proteins/pg/search_params.parquet, plus merged openms.* files.output dir
out_merged
Optional merged output file containing all PSMs pooled across input files with cross-file protein inference (BasicProteinInferenceAlgorithm) and optional picked-protein FDR (FDR:protein). Per-file outputs (-out_idxml / -out_qpx / -out_parquet) retain run-level information. Only useful with multiple -in files.output file*.idXML
out_pin[]
Output Percolator input (.pin/.tsv) file(s) for external rescoring. Must have the same number of entries as -in. Written independently of -percolator_executable (i.e. you can produce .pin files without running Percolator).output file*.tsv
out_mod_analysis_dir
Optional directory to write modification-analysis tables (delta-mass, PTM stats) when running in open-search mode. When set, per-file tables are written using each input file's basename and an additional aggregate table is written across all input files. Has no effect in closed-search mode.output dir
summary_out
Optional YAML file capturing the end-of-search report (per-file identification statistics, shared configuration/database/index facts, timing and output manifest) for pipeline ingestion. The same information is printed to the command line unless -no_summary is set.output file*.yaml
no_summaryfalse
Suppress the end-of-search report printed to the command line. The -summary_out YAML file (if requested) is still written.true, false
percolator_executable
Path to the Percolator executable. If set, per-file PSMs are rescored with Percolator (via PercolatorAdapter) before output. Leave empty to skip rescoring.input file
log
Name of log file (created only when specified)
debug0
Sets the debug level
threads1
Sets the number of threads allowed to be used by the TOPP tool (0 = all available cores)
no_progressfalse
Disables progress logging to command linetrue, false
forcefalse
Overrides tool-specific checkstrue, false
testfalse
Enables the test mode (needed for internal use only)true, false
+++Search
enzymeTrypsin
The enzyme used for peptide digestion.Formic_acid, Arg-C/P, iodosobenzoate, Chymotrypsin, Lys-C, cyanogen-bromide, Asp-N_ambic, no cleavage, unspecific cleavage, Lys-N, Lys-C/P, PepsinA, TrypChymo, proline-endopeptidase/HKR, Chymotrypsin/P, Trypsin/P, V8-DE, Asp-N, Trypsin, V8-E, leukocyte elastase, Asp-N/B, proline endopeptidase, glutamyl endopeptidase, Alpha-lytic protease, staphylococcal protease/D, Glu-C+P, PepsinA + P, CNBr, 2-iodobenzoate, Arg-C, Clostripain/P, elastase-trypsin-chymotrypsin
decoysauto
Decoy handling for target-decoy FDR. 'auto': ensure decoys are available — reuse decoys already present in the database (marker auto-detected, prefix or suffix) or generate them if none are found. 'generate': always (re)generate decoys from the target proteins (any pre-existing decoys are removed first to avoid decoy-of-decoy entries). 'ignore': search the target proteins only — any decoys present in the database are removed.auto, generate, ignore
decoy_prefixDECOY_
Accession prefix prepended to decoy proteins when ProSE generates them (modes 'auto' without existing decoys, and 'generate'). Pre-existing decoys in the database are detected automatically (any common marker, used as prefix or suffix) and do not require this setting.
snes_enabledfalse
[experimental, v1.1 opt-in] When peptide:enzyme_specificity=none, use mother-peptide indexing (Single-N + Single-C, one ion series per mother) instead of naïve O(L^2) sub-peptide enumeration. Much smaller index and faster search on non-specific workloads (immunopeptidomics). Ignored for specific/semi-specific enzymes. Variable modifications are supported in v1.1 via query-time subset enumeration on the realized sub-peptide.true, false
++++precursorPrecursor (Parent Ion) Options. mass_tolerance_lower/_upper are positive magnitudes applied as [-lower, +upper] around the precursor mass.
mass_tolerance_lower10.0
Lower-side precursor-mass tolerance (positive magnitude; effective window is [-lower, +upper] around the precursor). When strongly asymmetric, also review precursor:isotope_error_min.0.0:∞
mass_tolerance_upper10.0
Upper-side precursor-mass tolerance (positive magnitude).0.0:∞
mass_tolerance_unitppm
Unit of precursor mass tolerance.ppm, Da
min_charge2
Minimum precursor charge to be considered.
max_charge5
Maximum precursor charge to be considered.
isotopes[0, 1]
Corrects for mono-isotopic peak misassignments. (E.g.: 1 = prec. may be misassigned to first isotopic peak)
isotope_error_min-1
Minimum allowed precursor isotope error
isotope_error_max1
Maximum allowed precursor isotope error
++++fragmentFragments (Product Ion) Options
mass_tolerance20.0
Fragment mass tolerance
mass_tolerance_unitppm
Unit of fragment mppm, Da
deisotopeauto
MS2 deisotoping (single-charge deconvolution) before searching. 'auto' deisotopes only when the fragment tolerance is within the high-resolution deisotoper range (<= 0.1 Da / <= 100 ppm) and skips it for low-resolution (e.g. ion-trap CID) data; 'true' always deisotopes (requires a high-resolution fragment tolerance); 'false' never deisotopes.auto, true, false
min_mz150
Minimal fragment mz for database
max_mz2000
Maximal fragment mz for database
min_ion_index2
Ions with index less than or equal to this value are not added to the fragment index (use 0 to include all ions; 2 skips b1/b2/y1/y2). Low-index ions are often noisy and unreliable.0:∞
min_matched_ions5
Minimal number of matched ions to report a PSM
max_charge2
max fragment charge
++++peaks
keep_n0
Maximum number of MS2 peaks kept per spectrum (NLargest) before scoring. 0 = auto: a resolution-aware cap (~400 for high-res, ~80 at 0.5 Da, floor 60) that avoids the spurious low-resolution fragment matching which otherwise inflates HyperScore for targets and decoys alike. Set an explicit value to override (e.g. 400 for the legacy behavior).0:∞
window_top20
Maximum number of MS2 peaks kept per 100 Da window (WindowMower) before scoring.1:∞

++++peptidePeptide Options
min_size7
Minimum size a peptide must have after digestion to be considered in the search.
max_size40
Maximum size a peptide must have after digestion to be considered in the search (0 = disabled).
missed_cleavages1
Number of missed cleavages.
enzyme_specificityfull
Enzyme cleavage specificity required for both peptide termini.
'full' : both termini must be enzyme-specific (canonical, e.g. tryptic).
'semi' : only one terminus needs to be enzyme-specific (semi-tryptic).
'none' : no enzyme constraint at either terminus; every substring of length
[min_size, max_size] is enumerated. Use this for immunopeptidomics
(e.g. HLA peptides 8..12mers). For very large search spaces consider
tightening 'peptide:min_size'/'peptide:max_size'.full, semi, none

If set, only peptides that contain this motif (provided as RegEx) will be considered.

++++reportReporting Options
top_hits1
Maximum number of top scoring hits per spectrum that are reported.
++++FDRFalse Discovery Rate control (requires decoys)
PSM0.0
Filter PSMs based on q-value (e.g., 0.05 = 5% FDR, set to 0 to disable filtering and report all PSMs with q-values). Target and decoy PSMs are filtered alike by the q-value threshold; decoys that pass are kept (no decoy-specific stripping here — decoys are removed only at protein-FDR finalization). Requires '-decoys' to be set.0.0:1.0
protein0.0
Filter proteins based on picked-protein FDR q-value (e.g., 0.01 = 1% protein FDR, set to 0 to disable). Applied after PSM-level FDR on a complete protein set (single file, or the -out_merged aggregate). Setting this > 0 finalizes the result: identified decoys are removed. With 0, decoys are retained for downstream/merged FDR. Uses the picked-protein approach (Savitski et al. 2015) which pairs target and decoy proteins by accession. Requires '-decoys' to be set.0.0:1.0

++++calibrationAutomatic mass accuracy calibration (two-pass search). A fast first pass on a subset of spectra estimates instrument-specific mass accuracy, then the main search uses the calibrated (typically tighter) tolerances for better discrimination.
enabledfalse
If enabled, run a fast calibration pass on a subset of spectra before the main search. Estimates tighter precursor and fragment tolerances from confident PSMs. The fragment index is NOT rebuilt — only query-time tolerances are tightened. Inspired by MSFragger's calibrate_mass and OpenNuXL's autotune.true, false
subset_ratio0.1
Fraction of spectra (by TIC, highest first) used for the calibration pass (0.0-1.0).0.01:1.0
min_psms50
Minimum number of confident PSMs required for calibration. If fewer are found, calibration is skipped and the user-configured tolerances are used.1:∞
++++database
chunk_size0
Split the protein database into chunks of at most this many proteins for fragment index building. 0 = disabled (load entire database at once). Enable for very large databases (e.g. MHC-II immunopeptidomics with variants) that exceed available memory. Each chunk builds its own fragment index; results are merged across chunks before post-processing. Calibration (when enabled) runs on a strided, size-bounded sample of the full decoy-augmented database — sample size is tied to chunk_size so calibration memory respects the same budget as main-search chunks. In multi-file mode (-in a.mzML b.mzML), the chunk-major path builds each chunk's fragment index once and scores all files against it before moving to the next chunk.0:∞
