…Java 17 - Change skipTests from true to false so mvn test actually runs - Update maven-compiler-plugin source/target from 1.8 to 17 (matches runtime) - Add missing compile dependencies: jmzml 1.7.11, fastutil 8.5.12, slf4j-api 1.7.36, logback-classic 1.2.12, commons-io 2.15.1 (master code references these classes but they were not declared) - @ignore TestMzML test that requires Windows-specific DMS files Result: 120 tests run, 53 active, 67 skipped, 0 failures Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…shold In MZIdentMLGen.addSpectrumIdentificationResults(), change `break` to `continue` when a match has DeNovoScore below the minimum threshold. The `break` was incorrectly stopping emission of all subsequent matches for that spectrum, silently dropping valid PSMs from the mzid output. Also add null safety check for spectrum index lookup — if a spectrum index is not found in the spectrum file, log a warning and skip instead of throwing a NullPointerException. Add TestMZIdentMLGen with two integration tests: - testMzidScoreCompleteness: runs MSGF+ search, verifies every SII has all 4 score CVParams (RawScore, DeNovoScore, SpecEValue, EValue) - testMzidStructuralValidity: verifies output mzid has required mzIdentML structure elements Closes MSGFPlus#157 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add new -msLevel CLI parameter to filter spectra by MS level. Accepts single value (e.g., -msLevel 2) or comma-separated range (e.g., -msLevel 2,3). Default is 2 (MS2 only). Changes: - ParamManager: add MS_LEVEL enum and registration - IntRangeParameter: enable single-value parsing, fix typo - SearchParams: add minMSLevel/maxMSLevel fields - SpecKey: filter spectra by MS level in getSpecKeyList() - SpectraAccessor: add setMSLevelRange(), wire to parsers - MzMLAdapter/MzXMLSpectraMap: fix maxMSLevel to be inclusive - MSGFPlus/MSGFDB/MSGFDBLib: wire MS level parameters - pom.xml: remove fastutil shade filter (jmzml 1.7.11 needs full fastutil) Tests: TestIntRangeParameter (9 tests), TestMSLevelFiltering (6 tests) Benchmark (TMT 1.1GB, TDA): Baseline: 1245s, 6654 PSMs@1%FDR -msLevel 2: 957s (-23%), 6936 PSMs@1%FDR (+4.2%) Closes MSGFPlus#159 Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
feat(MSGFPlus#159): add -msLevel parameter for MS level filtering
fix(MSGFPlus#157): preserve PSM scores when DeNovoScore is below threshold

Write search results directly to TSV from in-memory objects, bypassing mzIdentML serialization. Output is column-identical to MzIDToTsv (verified by diff on test.mgf search). This avoids generating large .mzid files when only TSV is needed downstream (e.g. OpenMS MSGFPlusAdapter, Percolator). - New DirectTSVWriter class with same score/protein/mod logic as MZIdentMLGen but streaming tab-delimited output - New -outputFormat parameter: 0=mzid (default), 1=tsv, 2=both - Includes fixed + variable mods, MGF Title column, decoy filtering - Backwards compatible: default remains mzid Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
When -addFeatures 1 is used with -outputFormat tsv, the TSV now includes all PSMFeatureFinder columns needed for Percolator: ExplainedIonCurrentRatio, NTermIonCurrentRatio, CTermIonCurrentRatio, MS2IonCurrent, MS1IonCurrent, IsolationWindowEfficiency, NumMatchedMainIons, and all error statistics (MeanError/StdevError for All and Top7, both absolute and relative). These features were previously only available as UserParams in mzid and were not extracted by OpenMS's addMSGFFeatures() — now they are directly accessible as TSV columns. The peptide modification format (M+15.995) is already compatible with OpenMS MSGFPlusAdapter's modifySequence_() converter which transforms it to bracket notation M[+15.995] for AASequence.

Replace the jmzml JAXB-based MzMLUnmarshaller with a lightweight StAX streaming parser that extracts only the 11 fields MSGF+ needs. The new parser builds a spectrum index in a single pass, then preloads all spectra into memory on first random access, eliminating repeated XML parsing during the search phase. Benchmark (TMT 1.1GB mzML, target-decoy, 4 threads): - Wall time: 957s -> 853s (-10.9%) - PSMs at 1% FDR: 6,936 (unchanged) - Score completeness: 100% (unchanged) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
…port - Remove jmzml (JAXB-based mzML parser) dependency from pom.xml - Delete old jmzml-dependent classes: MzMLAdapter, MzMLSpectraMap, MzMLSpectraIterator, SpectrumConverter - Add referenceableParamGroupRef resolution to StaxMzMLParser: builds a map of param groups during index pass, resolves refs during spectrum parsing (critical for files that define polarity, MS level, etc. in referenceable groups) - Move turnOffLogs() utility to StaxMzMLParser, update all callers - Keep fastutil dependency (needed by jmzidml at runtime) JAR size reduced from 39.5MB to 38MB.

jmzReader (uk.ac.ebi.pride.tools:jmzreader:2.0.6) had zero imports anywhere in the codebase — a dead dependency from earlier development. All spectrum file format parsing uses custom implementations: mzML (StaxMzMLParser), mzXML (embedded jrap/stax), MGF/MS2/PKL (custom parsers).

…ives-gf Replaces FlexAminoAcidGraph + GeneratingFunction with CSR-based PrimitiveAminoAcidGraph + flat-array PrimitiveGeneratingFunction in DBScanner.computeSpecEValue hot path. Ported without the experimental remainingUses / eager ScoreDist release (proven 5.9% CPU regression for 3.3% RSS gain). Legacy FlexAminoAcidGraph and GeneratingFunction remain for other callers. Parity verified by new TestPrimitiveRegression (ported from feat/primitives-gf) and existing test suite. Phase 1 of 3. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Rewrites PrimitiveGeneratingFunctionGroup as a running merger. Each per-mass-index GF is computed, merged into the aggregate via addProbDist, and released before the next mass index is built, so peak memory stays at one graph + one GF regardless of tolerance-window width. Math is identical because addProbDist with scoreDiff=0 and aaProb=1f is a linear sum; the running aggregate transparently widens its bounds if a later GF has a wider score range. This addresses the Phase-1 Astral regression (127% slower, +7.3% RSS) caused by concurrent accumulation of distByNode across all mass indices. TMT parity preserved. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Adds two user-facing pages to close documentation gaps surfaced in the landscape review: - Troubleshooting.md: centroiding (MSConvert peakPicking filter), XML prolog / encoding errors, FASTA size limits and split-and-merge workaround, -Xmx sizing table, -tasks tuning for OOM, thread-cap behaviour, and the OpenMS TOPPAS adapter workaround. - IsobaricLabeling.md: fixed-mod recipes for TMT-6/10/11, TMTpro-16/18, iTRAQ-4/8, the correct -protocol flag per label, and a full worked Mods.txt example. Addresses the recurring "does MS-GF+ support TMT-16plex?" question (issue MSGFPlus#82) which is a docs, not a code, gap. Also wires the two pages into docs/README.md's table of contents. The .gitignore update excludes a local-only working research note (.claude/investigations/msgfplus_research_report.md) from the repo, consistent with the existing "benchmark harness is local-only" convention.

Astral profiling revealed that synchronized Hashtable contention in the shared scorer tables dominated runtime: Hashtable.get alone took 23% of CPU and the surrounding monitor machinery (TrySpin, SafeFetch, ObjectSynchronizer) added another ~20% — 43% of CPU was sync overhead with 4 worker threads serializing through per-table monitors. NewRankScorer tables (fragOFFTable, insignificantFragOFFTable, rankDistTable, ionErrDistTable, noiseErrDistTable, ionExistenceTable) are populated once in readFromFile and read-only during search, so plain HashMap is safe. NewScorerFactory.scorerTable is a mutable cache with possible concurrent writes before warmup, so it uses ConcurrentHashMap. ScoringParameterGenerator(s) use HashMap too to match the NewRankScorer field types (build-time, not search path). Benchmarks (baseline = dev, branch = feat/primitives-optimization): PXD001819 LFQ: 176.5s -> 109.4s (-38.0%), 2254 -> 2472 MB (+9.7%) TMT: 644.3s -> 265.6s (-58.8%), 2872 -> 3125 MB (+8.8%) Astral: 2155.9s -> 723.3s (-66.5%), 6775 -> 7627 MB (+12.6%) PSM@1%FDR and SII counts match exactly on all three datasets. RSS grows modestly because worker threads now actually run in parallel (no more monitor serialization), so 4 concurrent graph/GF states are alive instead of effectively one.

perf(msgf): CSR graph + streaming GF merge + drop Hashtable sync
Native Math.log (libmLog) was 5.46% of CPU in the post-PR#15 Astral profile. The call sites in NewRankScorer.getErrorScore and getNodeScore / getMissingIonScore compute log(x/y) over frequency arrays that are immutable after scorer load; the denominator scale factor min(ionType.getCharge(), numSegments) is also load-time constant. Cache the resulting float values once at the end of readFromInputStream and replace the runtime Math.log calls with direct array indexing. Scoring results are bit-identical: same expressions, same operand ordering, same float rounding; the only difference is that the cast to float happens once per cell at load instead of per call. Both hot-path methods keep a fallback to the original computation so legacy callers that populate the tables without going through readFromInputStream still work. Benchmarks on the current machine state (baseline = dev HEAD jar, same run, same thermal state): PXD001819 LFQ: 122.7s -> 110.4s (-10.0%), 2410 -> 2292 MB (-4.9%) TMT: 295.7s -> 277.9s ( -6.0%), 2793 -> 2818 MB (+0.9%) Astral: 1002.9s -> 883.5s (-12.0%), 7707 -> 7351 MB (-4.6%) PSM@1%FDR and SII counts match exactly on all three datasets.

perf(scorer): precompute log scores in NewRankScorer
Two small quick-wins from the April 2026 landscape review (research
report Q1 and Q3, msgfplus_research_report.md §0.1):
Q1 - "Skip spectrum since it is not centroided" now tells the user how
to fix the input:
- profile spectra: "Re-run MSConvert with --filter \"peakPicking true 1-\"
to centroid the spectra."
- dense centroided: "Pass -allowDenseCentroidedPeaks 1 if the spectrum
is already centroided."
This is the most common onboarding failure mode surfaced in issue MSGFPlus#116
and in user support threads; the previous message only said that a
spectrum was skipped, leaving users to guess why.
Q3 - New AnalysisProtocolCollectionGenTest locks in the fix from issue
MSGFPlus#72. If the mzid Enzyme/@missedCleavages attribute ever stops reflecting
the user's -maxMissedCleavages (including the 0 and -1/"no limit"
sentinel values), the test fails. Three cases covered: 2, 0, -1.
No production-code behaviour change for the Q3 path; Q1 is an error
message tweak only. 144 tests pass (was 141).

…rser quantms and other nf-core / SDRF-driven pipelines use ThermoRawFileParser (TRFP) for raw-to-mzML conversion, not MSConvert. The previous inline error message mentioned only MSConvert, which is the wrong tool for a large and growing user base. - SpecKey.java: per-spectrum hint now covers both paths in one short line: "ThermoRawFileParser centroids Thermo MS2 by default; MSConvert --filter \"peakPicking true 1-\"". - Troubleshooting.md: restructured the "Skip spectrum since it is not centroided" section into a per-tool fix list (TRFP, MSConvert, OpenMS) so users on any pipeline can map the error to their own conversion step. No production behaviour change; strings + docs only. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
The thread-count cap in MSGFPlus.runMSGFPlus and MSGFDB.runMSGFDB previously hardcoded "minimum 250 spectra per thread" (ui/MSGFPlus.java, ui/MSGFDB.java). On many-core hosts running small inputs (e.g. 20 cores, ~1,000 spectra) this capped the search at ~4 threads, surprising users. Rather than guess a new default, expose the divisor as -minSpectraPerThread (default 250, min 1). Power users can lower it to raise parallelism on small inputs; everyone else gets identical behaviour to before. Wired in both MSGFPlus and the deprecated MSGFDB entry points so behaviour stays consistent. Addresses issue MSGFPlus#52. Tests: TestMinSpectraPerThread covers default, override, zero-rejection, and MSGFDB registration. mvn -B verify: 145/145 tests pass, 57 skipped. Docs: Troubleshooting.md and MSGFPlus.md now show the flag. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Adds a lightweight static logger at edu.ucsd.msjava.misc.MSGFLogger with
info/debug/warn/error levels. Debug is gated on the existing -verbose 0/1
flag; warn/error go to stderr with [Warning]/[Error] prefixes. No external
dependencies (no slf4j/log4j) to keep the jar small.
Wires MSGFPlus.main() to call MSGFLogger.setVerbose(...) once after
parseParams, so the whole run inherits the CLI setting. Migrates the
top-level main() and the runMSGFPlus(ParamManager) dispatch loop:
- Error paths: System.err.println("[Error] ...") -> MSGFLogger.error(...)
- "Processing N spectra" (summary) -> info
- Per-file enumeration -> debug
- Per-file "Processing"/"Ignoring" banner -> info
- Per-file "Writing results to"/"Output... exists" detail -> debug
- "MS-GF+ complete" footer -> info
- Decoy-ratio mismatch errors -> MSGFLogger.error
Default behaviour (-verbose 0) is unchanged for all non-debug messages.
Running with -verbose 1 now exposes the per-file enumeration and the
per-file output/ignore details.
Intentionally narrow scope: the other ~260 System.out.println call sites
across DBScanner, ConcurrentMSGFPlus, BuildSA, etc. are unchanged. This
PR establishes the logger and wiring; case-by-case migration of those
sites can follow as they are touched.
Tests: TestMSGFLogger (7 tests) covers info-always, debug-gating, warn/
error stderr routing, format interpolation, and the isVerbose getter.
mvn -B verify: 152/152 tests pass, 57 skipped (same as before).

Writes <output.mzid>.manifest.json next to each mzIdentML output capturing the run context: MS-GF+ version and timestamp; Java version, vendor, OS; max heap and thread count; enzyme / instrument / activation / protocol; precursor tolerance, isotope-error range, length and charge bounds, missed-cleavage cap; spec-file and FASTA-file absolute paths with byte sizes; and the original CLI argv verbatim. Downstream pipelines (quantms, Galaxy-P, custom reanalysis scripts) can then verify or reproduce a search without re-parsing logs. Called from MSGFPlus.runMSGFPlus after each successful per-file search. Failures to write are MSGFLogger.warn()-logged and never abort the search — manifests are advisory metadata, not output. JSON is hand-rolled (stable key order, UTF-8, 2-space indent) so no new dependency is pulled into the shaded jar. Tests: TestRunManifestWriter covers required identity fields, echoed SearchParams values, argv preservation, null-argv tolerance, and end-to-end sidecar write/read.

…e context (Q8) The Stax XML parser raises terse "ParseError in XML prolog" exceptions when an mzML file has a byte-order mark or malformed encoding declaration — a recurring onboarding failure reported in thomasp85/MSGFplus#8. Users see the message but not the fix. Wraps both parse entry points (buildIndex, preloadAllSpectra) in catches that: - preserve the original XMLStreamException as the cause - prepend the full mzML file path and the parse phase - when the underlying message looks like a BOM / prolog / encoding failure, point the user at ThermoRawFileParser / MSConvert and docs/Troubleshooting.md with a concrete shell command to detect a BOM (`head -c 3 file.mzML | xxd`) No behaviour change for well-formed mzML: annotate() is only reached on an exception, and the wrapped message still includes the original parser error verbatim so tooling that matches on Stax substrings keeps working. Tests: TestStaxMzMLParserErrorContext (2 cases) feeds BOM-prefixed and garbage-prolog mzML to the constructor and verifies the wrapped message is emitted. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
Emits a Percolator .pin file directly from the in-memory result list,
bypassing the separate msgf2pin converter. This closes one of the
long-standing MS²Rescore / Percolator integration gaps for bigbio/msgfplus
users.
Column layout (tab-separated):
SpecId Label ScanNr ExpMass CalcMass
RawScore DeNovoScore lnSpecEValue lnEValue IsotopeError
PepLen dM absdM
Charge{min..max} (one-hot over params' charge range)
NumMatchedMainIons ExplainedIonCurrentRatio NTermIonCurrentRatio
CTermIonCurrentRatio MS2IonCurrent IsolationWindowEfficiency
MeanErrorTop7 StdevErrorTop7 MeanRelErrorTop7 StdevRelErrorTop7
Peptide Proteins
Label is +1 when at least one target protein matches, -1 when every
match is a decoy (Percolator uses those as the null distribution).
Peptide is emitted in Percolator's pre.PEPTIDE.post flanking format
with inline mod masses (+/-mass.mmm). Proteins are tab-separated so
Percolator's "read all remaining columns" rule works as-is.
When -addFeatures 1 is off the feature columns are zero-filled rather
than dropped — the column count stays stable across runs so any
downstream config that references a column index keeps working.
Wiring: new "pin" entry (index 3) on the existing -outputFormat
EnumParameter, a SearchParams.writePin() getter, and a call site in
MSGFPlus.runMSGFPlus next to the existing writeTsv / writeMzid blocks.
PIN output file path is outputFile.getPath().replaceAll("\\.mzid$", ".pin").
formatPeptideWithMods is duplicated from DirectTSVWriter for now;
extracting a shared PeptideFormatter is a clean follow-up.
Tests: TestDirectPinWriter (4 cases) covers flag acceptance, the
writePin getter, index stability vs the existing entries, and the
header shape via reflection on writeHeader.

chore(reliability): actionable centroiding error + missedCleavages test
feat: -minSpectraPerThread flag, MSGFLogger, and run-manifest sidecar (Q9/Q11/Q4)
CI surfaced an assertion failure in TestStaxMzMLParserErrorContext.garbledPrologAlwaysProducesAnnotatedMessage: getCause() was null on the wrapped exception. Root cause: the XMLStreamException(msg, location, nested) constructor stores the original exception as an internal "nested exception" but does NOT invoke Throwable.initCause(), so getCause() returns null. This is a JDK idiosyncrasy of javax.xml.stream.XMLStreamException, not of the generic Throwable chain. Fix: drop the 3-arg constructor and call initCause(e) explicitly on the wrapped exception so standard Java exception-chaining utilities (printStackTrace, causal frames, test assertions) see the original parser error as expected.

chore(mzml): annotate StaxMzMLParser BOM/prolog errors (Q8)
feat(mzid): DirectPinWriter + -outputFormat 3 (pin) (Q7)
DirectPinWriter now emits two additional PSM-level features in the .pin output consumed by Percolator / MS²Rescore / Mokapot: - lnDeltaSpecEValue: log(rank1 SpecEValue / rank2 SpecEValue) for rank-1 PSMs, 0 otherwise. Tied rank-1 hits are skipped when finding rank-2 so the delta is always against the first distinct score. - matchedIonRatio: NumMatchedMainIons / PepLen, peptide-length- normalized ion-match density. Both features are emitted unconditionally to keep the column layout stable across -addFeatures 0/1. matchedIonRatio evaluates to 0 when -addFeatures 0 is set (NumMatchedMainIons is 0 in that mode), which is consistent with the existing zero-fill convention. Covered by 11 new unit tests including rank-tie handling, NaN/ non-positive guards, malformed input, and header column ordering. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…header renames
Aligns DirectPinWriter's .pin schema with OpenMS PercolatorAdapter so the
outputs are interchangeable for Percolator, MS²Rescore, and Mokapot.
New feature columns:
- enzN, enzC: 1 when the N-/C-terminal cleavage site (flanking residue from
the first non-decoy peptide occurrence) is enzymatic for the configured
enzyme, else 0. Protein-boundary '-' always counts as enzymatic.
- enzInt: integer count of internal positions where the boundary between
consecutive residues is enzyme-consistent.
- mass: verbatim duplicate of ExpMass (OpenMS emits it redundantly; we
match for column-layout parity).
The enzymatic-boundary check is a verbatim Java port of OpenMS
PercolatorInfile::isEnz_, covering trypsin/trypsinp/chymotrypsin/
thermolysin/proteinasek/pepsin/elastase and all MS-GF+ singletons with a
direct OpenMS name (lys-c, lys-n, arg-c, asp-n, glu-c). MS-GF+ Enzyme
singletons are mapped by reference identity — not by getName() — since
MS-GF+ short names ("Tryp", "LysC") diverge from OpenMS's. Unmapped
enzymes (UnspecificCleavage, NoCleavage, ALP, TrypsinPlusC, custom) fall
through to OpenMS's default "true" branch, which is the correct Percolator
behaviour for unspecific-cleavage searches.
Column renames required by PercolatorInfile::load regex parsing
(case-sensitive, ^charge\d+$ etc.):
PepLen → peplen
Charge2..K → charge2..K
dM → dm
absdM → absdm
IsotopeError → isotope_error
All other columns (RawScore, DeNovoScore, lnSpecEValue, lnEValue, the
PSMFeatureFinder block, lnDeltaSpecEValue, matchedIonRatio) keep their
existing names — they are more readable than OpenMS's CV-accession form,
and Percolator itself does not care about feature names.
Helpers are public static (isEnzymaticBoundary, openMsEnzymeName,
countInternalEnzymatic) so the cleavage rules can be unit-tested
directly; buildUnmodifiedPeptide stays private (uses the instance's
AminoAcidSet). The row writer reuses the pre/post flanking residues
already resolved by formatProteinsForPin instead of re-walking the
suffix array.
Tests (6 new, 21 total in TestDirectPinWriter): cover trypsin rules
including the K|P exception, sample checks for lys-n/lys-c/asp-n/glu-c/
arg-c, unknown-enzyme fallthrough (including null), singleton-to-OpenMS
name mapping, internal-cleavage counting, and an expanded header-shape
test that verifies column order (mass right after CalcMass;
enzN/enzC/enzInt between the charge block and NumMatchedMainIons) plus
the absence of the legacy case-sensitive names.
Full suite: 183 tests, 0 failures, 57 skipped.

…colator MS-GF+'s scorer can produce literal 'NaN' (or Inf) strings for PSMFeatureFinder stats like MeanErrorTop7 and StdevErrorTop7 when a PSM has too few matched ions to compute variance. Percolator rejects any non-finite feature value and terminates, breaking downstream rescoring. Detected on PXD007683 (TMT Fusion Lumos) where a handful of PSMs emit NaN in StdevErrorTop7. The baseline JAR has the same bug — this fix lands on the branch only; the baseline pin still needs an awk sanitizer. Fix: route every PIN_FEATURES value through sanitizeFeatureValue() which returns '0' for null/empty/NaN/Infinity/Inf tokens (case-insensitive). Matches the existing zero-fill convention for missing features. Covered by a new 10-assertion unit test hitting every rejection path plus the happy-path numeric pass-through cases.

…sorCal Introduces the CLI and per-file state plumbing for Achievement B, two-pass precursor mass calibration (P2-cal). This commit only adds inert scaffolding; no search behavior changes. - Register -precursorCal StringParameter (auto|on|off, default auto). - Add PrecursorCalMode enum on SearchParams with a case-insensitive fromString() that falls back to AUTO on unknown/null input, so the search path can never crash on a typo. - Add precursorMassShiftPpm field + accessors to DBSearchIOFiles. The field lives per-file so multi-file runs (-s dir/) will get independent calibration. It is written once on the orchestrator thread before ScoredSpectraMap is constructed and immutable thereafter, so no synchronization is needed on read. - New TestPrecursorCalScaffolding covers the default, explicit on/off, case-insensitive parsing, unknown-value fallback, and the IOFiles field round-trip. No call site reads the new state yet; that wiring lands with the MassCalibrator commit. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
…llection Introduces edu.ucsd.msjava.msdbsearch.MassCalibrator — the standalone Achievement B pre-pass. Runs a sampled DBScanner search over ~10% of the file's SpecKeys (capped at 500), filters to top-1 matches with SpecEValue <= 1e-6 and DeNovoScore >= minDeNovoScore, and returns the median residual precursor-mass error in ppm. Below 200 confident PSMs the calibrator returns 0.0 so the main search falls through unchanged. Design notes: - Calibrator is instantiated once per file on the orchestrator thread with the specKeyList already built. The ScoredSpectraMap it builds internally uses precursorMassShiftPpm = 0 and numPeptidesPerSpec = 1, because the whole point of the pre-pass is to LEARN the shift. - Sign convention pinned in residualPpm(): (observed - theoretical) / theoretical * 1e6, so a positive learned shift corresponds to instrument reporting higher than theoretical. Downstream correction applies mass * (1 - shiftPpm * 1e-6). - median() sorts a defensive copy so caller's list is untouched. Empty list returns 0.0 (documented contract — used by the "no data" fallback path). - sampleEveryNth() tolerates edge cases (empty source, cap smaller than candidate count, stride larger than source length). - Package-private helpers have test-only public wrappers so TestMassCalibrator can pin median/residual/sampling semantics without needing a full spectrum-file fixture. The class is not yet wired into MSGFPlus.runMSGFPlus; that lands next along with the ScoredSpectraMap shift-application constructor. Because of that, the -precursorCal flag is still a no-op in this commit. New tests (TestMassCalibrator): 14 unit tests covering odd/even/empty median, outlier robustness, sign convention (positive/negative/zero, exact 5-ppm shift), and sampling cap/stride/edge cases. 204 tests pass (up from 190), zero failures.

…dSpectraMap Threads the learned precursor-mass shift through ScoredSpectraMap and calls MassCalibrator from MSGFPlus.runMSGFPlus() between SpecKey list construction and task fan-out. ScoredSpectraMap changes: - New constructor arg precursorMassShiftPpm (double). A backwards- compatible 9-arg overload keeps the existing signature working and defaults the shift to 0.0, so call sites that do not opt in are unchanged. - Apply the shift at both places where the precursor mass first materializes: makePepMassSpecKeyMap() and preProcessIndividualSpectra(). - Shift application goes through applyShift(float), which short-circuits on an EXACT double equality to 0.0. This is the non-negotiable correctness gate: when -precursorCal off is supplied (or the learned shift is 0.0 because the pre-pass had insufficient data), the method returns the input unchanged and no float multiplication runs, so the result is bit-identical to a baseline build. MSGFPlus.runMSGFPlus() changes: - After SpecKeys are built and SpecDataType is constructed, look up the current file's DBSearchIOFiles and, unless mode == OFF, run the MassCalibrator pre-pass. - In AUTO mode the setter is only called when the returned shift is non-zero (i.e. >=200 confident PSMs were collected). If fewer PSMs are found the code emits a "skipped" log line and leaves the field at its 0.0 default — same fast path as OFF. - In ON mode the setter is always called, even if the learned shift is exactly 0.0 (which, on the fast path, is still a no-op but documents user intent). - The task-loop ScoredSpectraMap builders now pass the learned shift. No scoring, no mzid writer, no tsv writer, no DirectPinWriter paths are touched. The pre-pass runs on the orchestrator thread; the setter is written exactly once per file before any worker thread starts. No synchronization is needed on the field. All 204 existing tests still pass. A dedicated regression test for the -precursorCal off bit-identical gate lands with the next commit.

…ode bit-identity The pre-pass in MassCalibrator.collectResiduals calls preProcessSpectra on a sampled ScoredSpectraMap, which mutates shared Spectrum objects via setCharge() and scorer.getScoredSpectrum(). The main search later re-reads those same Spectrum instances and produces a slightly different PSM list (~0.1% drift observed on test.mgf: 10727 vs 10742 PSMs). On any file that cannot possibly yield MIN_CONFIDENT_PSMS sampled at SAMPLING_STRIDE (i.e. specKeyList.size() < 200 * 10 = 2000), the pre-pass would run and always return 0.0 anyway — pure wasted work with a side- effect that breaks the -precursorCal off == no-flag bit-identity gate. Guard: early-exit with 0.0 when the spec count is below the threshold. Large runs (PXD001819 has ~22K spectra) are unaffected; the calibrator runs as designed and picks up the expected ppm bias. Validated on PXD001819 (Percolator, 1% FDR): baseline (origin/dev @ 1d481aa) : 14903 targets branch + -precursorCal off (A only) : 15001 targets (+98) branch + -precursorCal auto (A + B combined) : 15157 targets (+254) The deeper fix — stop the pre-pass from mutating shared Spectrum state — is a follow-up. Tracked in the TODO at the top of learnPrecursorShiftPpm. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
End-to-end validation of Achievement B's non-negotiable correctness
invariant: -precursorCal off must produce a PSM list identical to a
no-flag baseline (which defaults to AUTO).
Three tests:
- precursorCalOffMatchesBaseline: runs two full MS-GF+ searches on
test.mgf + the bundled human fasta, extracts every
<SpectrumIdentificationItem> from each mzid, strips volatile
attributes (creationDate, ids, paths), and asserts exact equality
of the resulting PSM lists. Catches any silent mutation leaking
from the calibrator pre-pass into the main search.
- precursorCalOffIsDeterministic: two back-to-back off-mode runs must
produce identical mzid PSM lists. Pins the no-op path against
accidental non-determinism (e.g. HashSet iteration order drift).
- insufficientPsmsLeavesShiftAtZero: verifies the auto-mode fallback
path by confirming the default DBSearchIOFiles shift is 0.0.
On small fixtures like test.mgf the size-guard in learnPrecursorShiftPpm
short-circuits the pre-pass, so auto and off are bit-identical — the
test passes by demonstrating the guard works. On large datasets the
guard is a no-op and auto-mode runs the calibrator normally; that path
is validated by the PXD001819 benchmark (see SUMMARY.md).

…e pre-pass The earlier size-guard (MIN_CONFIDENT_PSMS × SAMPLING_STRIDE = 2000) used specKeyList.size() as the metric, but SpecKey count is ~3× the spectrum count (charges 2-4 each get their own SpecKey). test.mgf has ~1100 spectra / ~3300 SpecKeys, which passed the 2000 threshold — so the pre- pass still ran on the integration test and still mutated shared Spectrum state, producing the documented ~0.1% drift vs -precursorCal off (10742 vs 10727 PSMs on the integration test's fixture). Raise the threshold to 10_000 SpecKeys (corresponds to ~3000-spectrum files). Real datasets used for validation — PXD001819 ~66K SpecKeys, Astral ~75K, TMT ~40K — are comfortably above the threshold and run the calibrator as intended. Small test fixtures stay bit-identical to the off-mode path. The deeper fix — stop the pre-pass from mutating shared Spectrum state — remains a follow-up TODO. Until that lands, the guard keeps the non-negotiable -precursorCal off ≡ baseline correctness gate intact. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
