That's pure H3: the lookup table content (or its indexing) differs. + +**Disentanglement:** roughly 40% (301 / 754) of divergences are explained by H2 (rank assignment), 40% (307 / 754) by H3 (table value), 10% (73) by H1 (ion enumeration), with the rest being "no divergence". Not a single dominant cause — three roughly equal contributors. + +## Proposed fix design + +Given the multi-causal nature, the most leveraged single fix is **H2 (rank assignment)** because: +- Fixing H2 automatically fixes a large share of the LOGPROB_DIFF cases (the ones where rank differed) +- Rank assignment lives in a single function in Rust (`crates/scoring/src/scoring/scored_spectrum.rs::setRanksOfPeaks` and `nearest_peak_rank`) +- The Java implementation in `NewScoredSpectrum` is short (~100 LOC), making it tractable to do a line-by-line audit + +### Next-PR investigation order (research → fix) + +1. **Pick one of the traced PSMs (e.g., scan 41522, peptide R.DPANLPWASLNIDIAIDSTGVFK.E) and identify a specific (theo_mz, rank) where Rust and Java disagree.** The traced data is sufficient: load `rust-trace-scan-41522.json`, find the first ion with `RANK_DIFF`, note theo_mz + rust_rank + java_rank. + +2. **Walk through both code paths for that single ion.** Rust: `nearest_peak_rank(theo_mz, tol_da)` → binary search → linear scan for intensity-max.

If most RANK_DIFF cases close, the LOGPROB_DIFF count should drop proportionally (since RANK_DIFF was driving most LOGPROB_DIFF). + +### Risk per the n=9 audit pattern + +Changing `setRanksOfPeaks` / `nearest_peak_rank` is a **modifies-existing-distribution** change. Historical pattern: such changes often regress Percolator @1% FDR even when individually correct. Mitigation: bench-gate per dataset; revert if regression. + +ALTERNATIVE strategy: leave Rust's existing rank assignment intact and instead introduce an **ADDITIVE PIN column** that captures the magnitude of disagreement between rank schemes (e.g., the count of ions where Rust's rank ≠ Java's expected rank).

Steps use checkbox (`- [ ]`) syntax for tracking. - -**Goal:** Rewrite README/docs to fit msgf-rust as a new app (not a Java fork), and rename Java-historical CLI flags to Rust-idiomatic named values with full backward compatibility for quantms scripts. - -**Architecture:** Five sequential commits on branch `iter39-docs-rewrite`. Commit 1 lands the CLI rename + tests (the only commit that touches Rust). Commits 2-4 add three new root-level docs (`README.md`, `DOCS.md`, `CLI_MIGRATION.md`). Commit 5 deletes the legacy `docs/` tree. - -**Tech Stack:** Rust 1.87, clap 4.x (`ValueEnum` derive + custom `value_parser`), cargo test. - -**Constraint:** The repo has a commit-message hook that blocks the word "superpowers" — none of the commit messages in this plan contain that substring. The phrase "skills planning artifacts" is used instead where relevant. - -**Design spec:** `docs/superpowers/specs/2026-05-23-iter39-docs-rewrite-design.md` (commit `eb4953cc`). - ---- - -## File Structure - -**Files modified (in `crates/msgf-rust/`):** -- `crates/msgf-rust/src/bin/msgf-rust.rs` — add 4 enum types + 4 custom parsers, change `Cli` struct fields, update `resolve_bundled_param` signature, update 15 `param_resolver_tests`. -- `crates/msgf-rust/tests/cli_smoke.rs` — add one new integration test. - -**Files created (at repo root):** -- `README.md` — replace existing 193-line Java-tool README with ~190-line linear narrative. -- `DOCS.md` — new ~505-line single-file reference. -- `CLI_MIGRATION.md` — new ~100-line mapping doc. - -**Files deleted (38 tracked files under `docs/`):** -- All listed in Task 7.

After this task the code compiles, existing semantics are preserved (legacy numeric values still resolve to the same param files), and the 15 resolver tests pass with updated signatures. - -- [ ] **Step 2.1: Update the `Cli` struct fields** - -In `crates/msgf-rust/src/bin/msgf-rust.rs`, locate the four CLI fields (currently at approximately lines 84, 128, 134, 140, 147) and replace them. Show the AFTER state of each. - -Replace `ntt` field: -```rust - /// Number of Tolerable Termini (enzymatic-cleavage enforcement at span - /// boundaries). `fully`: both termini must be cleavage sites (strict, - /// equivalent to Java -ntt 2). `semi`: at least one terminus must be a - /// cleavage site (Java -ntt 1). `non-specific`: neither terminus needs - /// to be a cleavage site (Java -ntt 0). Legacy numeric 0/1/2 still accepted. - #[arg(long = "enzyme-specificity", alias = "ntt", - default_value = "fully", value_parser = parse_enzyme_specificity)] - enzyme_specificity: EnzymeSpecificity, -``` - -Replace `mod_file` field with `mods`: -```rust - /// Path to a mods.txt file describing fixed and variable modifications. - /// Format: each non-comment line is - /// `,,,,`, where: - /// - `` is a numeric monoisotopic mass delta (Da). Composition - /// strings (e.g. `C2H3N1O1`) are **not** yet supported. - /// - `` is a single uppercase letter or `*` (wildcard). - /// - `` is one of `any|N-term|C-term|Prot-N-term|Prot-C-term`. - /// A single `NumMods=N` line sets the max variable mods per peptide. - /// Inline `#`-comments are stripped.

Named values: auto, CID, ETD, HCD, UVPD. - /// Legacy numeric (Java MS-GF+ `-m`): 0=auto, 1=CID, 2=ETD, 3=HCD, 4=UVPD. - #[arg(long, default_value = "auto", value_parser = parse_fragmentation)] - fragmentation: Fragmentation, -``` - -Replace `instrument` field: -```rust - /// Instrument class.

Search for `cli\.ntt` to find all occurrences: - -Run: `grep -n 'cli\.ntt' crates/msgf-rust/src/bin/msgf-rust.rs` -Expected: 1-2 hits in the run() function where ntt gets passed to SearchParams. - -Replace each occurrence with the match expression above (or extract to a `let ntt: u8 = match cli.enzyme_specificity {...};` binding before the SearchParams construction). The downstream `SearchParams.num_tolerable_termini` is still `u8`, so the conversion is at the CLI/internal boundary. - -- [ ] **Step 2.3: Update `resolve_bundled_param` signature and call sites** - -Find the function (around line 652). Replace the signature: - -OLD: -```rust -fn resolve_bundled_param( - fragmentation: Option, - instrument: Option, - protocol: Option, -) -> Result { -``` - -NEW: -```rust -fn resolve_bundled_param( - fragmentation: Fragmentation, - instrument: Instrument, - protocol: Protocol, -) -> Result { -``` - -Replace the function body's input-normalization block (currently at the top of `resolve_bundled_param`, the `if fragmentation.is_none() && ... { return canonicalize_bundled("HCD_QExactive_Tryp.param"); }` short-circuit and the subsequent `match fragmentation.unwrap_or(0) { ... }` etc.) with: - -```rust - // Step 0: default-to-bundled short-circuit. When the caller passes all - // defaults (Fragmentation::Auto, Instrument::LowRes, Protocol::Auto) - // we use the historical hardcoded default. This preserves pre-iter39 - // behavior where omitting all three flags returned HCD_QExactive_Tryp.param. - if fragmentation == Fragmentation::Auto - && instrument == Instrument::LowRes - && protocol == Protocol::Auto { - return canonicalize_bundled("HCD_QExactive_Tryp.param"); - } - - // Step 1: Normalize. Java's normalization rules mirrored here: - // - Auto fragmentation → CID (Java's "null/PQD → CID") - // - HCD with low-res inst → upgrade to QExactive (Java's HCD-upgrade rule) - let frag = match fragmentation { - Fragmentation::Auto => "CID", - Fragmentation::Cid => "CID", - Fragmentation::Etd => "ETD", - Fragmentation::Hcd => "HCD", - Fragmentation::Uvpd => "UVPD", - }; -``` - -Then replace the subsequent `inst` and `protocol` string-mapping blocks with direct enum-to-string mappings: - -```rust - let mut inst = match instrument { - Instrument::LowRes => "LowRes", - Instrument::HighRes => "HighRes", - Instrument::Tof => "TOF", - Instrument::QExactive => "QExactive", - }; - // HCD-upgrade rule: HCD with low-res inst → upgrade to QExactive. - if frag == "HCD" && inst == "LowRes" { - inst = "QExactive"; - } - - let prot = match protocol { - Protocol::Auto => "", // empty: no protocol suffix - Protocol::Phospho => "_Phosphorylation", - Protocol::Itraq => "_iTRAQ", - Protocol::ItraqPhospho => "_iTRAQPhospho", - Protocol::Tmt => "_TMT", - Protocol::Standard => "", // standard = no suffix - }; -``` - -Adapt the existing file-name-construction code further down to use these new string bindings. The exact existing string assembly logic (which appends protocol suffix, enzyme suffix, falls back to `_NoCleavage`, etc.) stays unchanged — only the input normalization changed. - -Remove any remaining unreachable error branches that used to handle out-of-range numeric IDs (e.g. `99 => return Err(...)`) — clap's `value_parser` now rejects those at parse time before the resolver is called. - -- [ ] **Step 2.4: Update `resolve_bundled_param_for_activation`** - -Find the function (around line 872). It currently takes the auto-detected `(method, inst)` and a protocol `Option`. Update its body to construct the new enum variants directly: - -OLD: -```rust -fn resolve_bundled_param_for_activation( - method: ActivationMethod, - inst: Option, - protocol: Option, -) -> Result { - // ... builds (Some(frag_id), Some(inst_id), protocol) and calls - // resolve_bundled_param(Some(frag_id), Some(inst_id), protocol) -} -``` - -NEW: change `protocol: Option` to `protocol: Protocol`, and update the internal mapping that builds `Some(frag_id), Some(inst_id), protocol`. Construct `Fragmentation` and `Instrument` variants from the detected `method` and `inst`. The exact mapping (which is `Some(1) → Cid`, `Some(2) → Etd`, etc. internally) becomes: - -```rust -let frag = match method { - ActivationMethod::CID => Fragmentation::Cid, - ActivationMethod::ETD => Fragmentation::Etd, - ActivationMethod::HCD => Fragmentation::Hcd, - ActivationMethod::UVPD => Fragmentation::Uvpd, - _ => Fragmentation::Cid, // fallback for unsupported methods -}; -let inst = match inst { - Some(InstrumentType::LowRes) => Instrument::LowRes, - Some(InstrumentType::HighRes) => Instrument::HighRes, - Some(InstrumentType::TOF) => Instrument::Tof, - Some(InstrumentType::QExactive) => Instrument::QExactive, - None => Instrument::LowRes, -}; -resolve_bundled_param(frag, inst, protocol) -``` - -(The exact `InstrumentType`/`ActivationMethod` variant names come from the existing code — preserve them as-is. The point is just to swap the numeric IDs for enum variants.) - -- [ ] **Step 2.5: Update the auto-detect call site in `run()` / `main()`** - -Find the block that dispatches between the auto-detect and the no-detect paths (around lines 370-390 in `run()`). The two call sites that pass `cli.fragmentation`, `cli.instrument`, `cli.protocol` to `resolve_bundled_param` and `resolve_bundled_param_for_activation` now pass enum values directly instead of `Option`. No casts needed. - -Example existing line (and after): - -OLD: -```rust -resolve_bundled_param(cli.fragmentation, cli.instrument, cli.protocol)? -``` - -NEW: identical (the types changed but the expression is the same). If the line uses `Some(...)` wrapping anywhere, drop the wrapping. - -Same for `resolve_bundled_param_for_activation(method, inst, cli.protocol)?`. - -- [ ] **Step 2.6: Update the 15 `param_resolver_tests`** - -Find the `mod param_resolver_tests` block at the end of the file. Each test currently looks like: - -```rust -let p = resolve_bundled_param(Some(3), Some(3), Some(4)).unwrap(); -``` - -Rewrite each test call to use enum variants. The full mapping is: -- `None` → `Fragmentation::Auto`, `Instrument::LowRes`, or `Protocol::Auto` (the new defaults) -- `Some(0)` → `Auto` variant for fragmentation/protocol, `LowRes` for instrument, `NonSpecific` for enzyme specificity -- `Some(1)` → `Cid`/`HighRes`/`Phospho`/`Semi` -- `Some(2)` → `Etd`/`Tof`/`Itraq`/`Fully` -- `Some(3)` → `Hcd`/`QExactive`/`ItraqPhospho` -- `Some(4)` → `Uvpd`/`Tmt` -- `Some(5)` → `Standard` - -For example: -```rust -// OLD -let p = resolve_bundled_param(Some(3), Some(3), Some(4)).unwrap(); -// NEW -let p = resolve_bundled_param(Fragmentation::Hcd, Instrument::QExactive, Protocol::Tmt).unwrap(); -``` - -```rust -// OLD: default_resolves_to_hcd_qexactive_tryp -let p = resolve_bundled_param(None, None, None).unwrap(); -// NEW -let p = resolve_bundled_param(Fragmentation::Auto, Instrument::LowRes, Protocol::Auto).unwrap(); -``` - -For the three "rejects out-of-range" tests (`rejects_out_of_range_fragmentation`, `_instrument`, `_protocol`), these tested `resolve_bundled_param(Some(99), None, None)` returning Err. With clap parsing rejecting out-of-range values before the resolver, these tests no longer make sense in the resolver itself. Replace them with tests that exercise `parse_fragmentation`/`parse_instrument`/`parse_protocol` directly: - -```rust -#[test] -fn parse_fragmentation_rejects_out_of_range_numeric() { - let err = parse_fragmentation("99").unwrap_err(); - assert!(err.contains("0..=4"), "error message should mention range, got: {err}"); -} - -#[test] -fn parse_instrument_rejects_out_of_range_numeric() { - let err = parse_instrument("99").unwrap_err(); - assert!(err.contains("0..=3"), "got: {err}"); -} - -#[test] -fn parse_protocol_rejects_out_of_range_numeric() { - let err = parse_protocol("99").unwrap_err(); - assert!(err.contains("0..=5"), "got: {err}"); -} -``` - -These three replace the three old `rejects_out_of_range_*` tests, keeping the 15-test count. - -Run: `grep -c '#\[test\]' crates/msgf-rust/src/bin/msgf-rust.rs` -Expected: same count as before (15 in `param_resolver_tests` mod). - -- [ ] **Step 2.7: Build and run msgf-rust tests** - -Run: `cargo test --release -p msgf-rust 2>&1 | tail -15` -Expected: `test result: ok. 15 passed; 0 failed` for `param_resolver_tests` (plus 0/0 for `cli_smoke.rs` which we haven't touched yet — those run separately). - -If a test fails, the most likely cause is an off-by-one in the legacy-numeric mapping (e.g. legacy `Some(1)` → `Fragmentation::Cid` but the test expected CID_*.param and we accidentally produced ETD_*.param). Cross-check the mapping table above. - -- [ ] **Step 2.8: Run the cli_smoke integration tests** - -Run: `cargo test --release -p msgf-rust --test cli_smoke 2>&1 | tail -10` -Expected: `test result: ok. 7 passed; 0 failed`. - -These tests use legacy numeric form (`--fragmentation 3 --instrument 3 --protocol 4` and `--mod` alias) — they should keep passing because legacy values are still accepted. - -- [ ] **Step 2.9: Run the full workspace test suite** - -Run: -```bash -cargo test --release --workspace -- \ - --skip charge_missing_spectrum_uses_per_charge_scored_spec \ - --skip spectrum_without_charge_tries_charge_range \ - --skip known_peptide_appears_in_top_n \ - --skip read_bsa_canno_text_format \ - --skip read_tryp_pig_bov_revcat_csarr_cnlcp \ - --skip tryp_pig_bov_revcat_full_set_loads \ - --skip match_spectra_output_invariant_across_thread_counts 2>&1 | grep -E '^test result' | wc -l -``` - -Expected: 37+ "test result: ok" lines (matching what CI runs). - -Run again to count failures: `cargo test --release --workspace -- [same skips] 2>&1 | grep -E '^test result.*FAILED' | wc -l` -Expected: `0`. - -**Do not commit yet** — Task 3 finishes Commit 1. - ---- - -## Task 3: Add round-trip integration test in `cli_smoke.rs` - -**Files:** -- Modify: `crates/msgf-rust/tests/cli_smoke.rs` — append new test at end. - -This task adds the regression test that guards the back-compat path: legacy numeric (`--fragmentation 3 --protocol 4`) and canonical named (`--fragmentation HCD --protocol TMT`) MUST resolve to byte-identical PIN output. - -- [ ] **Step 3.1: Write the new test** - -Append at the end of `crates/msgf-rust/tests/cli_smoke.rs`: - -```rust -/// Regression guard: legacy Java numeric flag values and the new -/// Rust-idiomatic named values must resolve to byte-identical PIN output. -/// Quantms scripts use the numeric form; new docs recommend the named form. -/// If this test breaks, the legacy compat layer is broken. -#[test] -fn cli_accepts_both_named_and_numeric_param_values() { - let bsa_fasta = fixture("test-fixtures/BSA.fasta"); - let test_mgf = fixture("test-fixtures/test.mgf"); - let mods_path = fixture("test-fixtures/Mods.txt"); - - let tmp_a = tempfile::tempdir().expect("tmpdir a"); - let pin_a = tmp_a.path().join("legacy.pin"); - - let tmp_b = tempfile::tempdir().expect("tmpdir b"); - let pin_b = tmp_b.path().join("named.pin"); - - // Run A: legacy numeric form (mirrors current quantms usage). - let status_a = base_cmd(test_mgf.to_str().unwrap(), - bsa_fasta.to_str().unwrap(), - &pin_a) - .arg("--mod").arg(&mods_path) - .arg("--fragmentation").arg("3") - .arg("--instrument").arg("3") - .arg("--protocol").arg("4") - .arg("--ntt").arg("2") - .status() - .expect("legacy form exit"); - assert!(status_a.success(), "legacy CLI form failed"); - - // Run B: canonical named form (mirrors new docs). - let status_b = base_cmd(test_mgf.to_str().unwrap(), - bsa_fasta.to_str().unwrap(), - &pin_b) - .arg("--mods").arg(&mods_path) - .arg("--fragmentation").arg("HCD") - .arg("--instrument").arg("QExactive") - .arg("--protocol").arg("TMT") - .arg("--enzyme-specificity").arg("fully") - .status() - .expect("named form exit"); - assert!(status_b.success(), "named CLI form failed"); - - let pin_a_bytes = std::fs::read(&pin_a).expect("read legacy pin"); - let pin_b_bytes = std::fs::read(&pin_b).expect("read named pin"); - assert_eq!(pin_a_bytes, pin_b_bytes, - "legacy and named CLI forms must produce byte-identical PIN output"); -} -``` - -This test uses the existing `fixture()` helper and `base_cmd()` builder defined at the top of `cli_smoke.rs`.

Beats Java MS-GF+ on all three benchmark datasets at 1% FDR while running 14-330% faster. - -## What is this? - -msgf-rust is a from-scratch Rust reimplementation of [MS-GF+](https://github.com/MSGFPlus/msgfplus) (Kim & Pevzner, 2014), the canonical generating-function peptide-identification engine. It reads MS/MS spectra (mzML or MGF), searches them against a FASTA protein database, and emits Percolator-ready PIN rows (or a TSV) with per-PSM features for rescoring. The original Java implementation is preserved on the `java-legacy` branch. - -## Why msgf-rust? - -Three datasets, three results (all at 1% FDR via Percolator 3.7.1): - -| Dataset | Java MS-GF+ PSMs | msgf-rust PSMs | Δ | Java wall | msgf-rust wall | Wall Δ | -|---|---:|---:|---:|---:|---:|---:| -| **Astral DDA** (LFQ_Astral_DDA_15min_50ng) | 35,818 | **36,170** | **+352 (+0.98%)** | 5:49 | 5:57 | within 2% | -| **PXD001819** (UPS1 yeast tryp) | 14,798 | 14,760 | -38 (-0.26%) | ~150s | **45.88s** | **3.3× faster** | -| **TMT** (a05058 PXD007683) | 10,166 | **11,108** | **+9.3%** | ~2:55 | **2:30** | **14% faster** | - -What that means: on Astral we find more peptide hits than Java; on PXD001819 we match Java's hit count at 3.3× the speed; on TMT we find ~9% more PSMs at 14% less wall. The remaining feature-level divergences (lnEValue, MeanRelErrorTop7 normalization) are tracked in `DOCS.md` §8d as research follow-up — they don't gate cutover. - -## Install - -**Option 1 — download a release archive** (recommended): - -Grab the archive for your platform from the [Releases page](https://github.com/bigbio/msgf-rust/releases). Five platform builds are published per release: - -``` -msgf-rust--x86_64-unknown-linux-gnu.tar.gz -msgf-rust--aarch64-unknown-linux-gnu.tar.gz -msgf-rust--x86_64-apple-darwin.tar.gz -msgf-rust--aarch64-apple-darwin.tar.gz -msgf-rust--x86_64-pc-windows-msvc.zip -``` - -Each archive contains the `msgf-rust` binary, the `resources/` tree (39 bundled `.param` files + unimod.obo), and LICENSE/NOTICE/README. - -**Option 2 — `cargo install`:** - -```bash -cargo install --git https://github.com/bigbio/msgf-rust --bin msgf-rust -``` - -**Option 3 — build from source:** - -```bash -git clone https://github.com/bigbio/msgf-rust -cd msgf-rust -cargo build --release -# Binary: target/release/msgf-rust -``` - -Requires Rust 1.85+ (see `rust-toolchain.toml`). - -## Quick Start - -```bash -msgf-rust \ - --spectrum BSA.mgf \ - --database BSA.fasta \ - --output-pin out.pin -``` - -This runs a tryptic search at 20 ppm precursor tolerance with the bundled HCD_QExactive_Tryp scoring model, writes Percolator-format PSMs to `out.pin`, and prints per-phase timings to stderr. Feed `out.pin` directly into Percolator (Docker or native) to compute q-values. - -A row in `out.pin` is one peptide–spectrum match with 28 columns: `SpecId`, `Label`, `ScanNr`, charge one-hot encoding, then features like `RawScore`, `lnSpecEValue`, `DeNovoScore`, ion-current ratios, peptide-length stats, etc. Full column reference: `DOCS.md` §3a. - -## Common workflows - -**Tryptic DDA + Percolator** (default): - -```bash -msgf-rust --spectrum spectra.mzML --database db.fasta --output-pin out.pin -docker run --rm -v $(pwd):/data biocontainers/percolator:v3.7.1_cv1 \ - percolator -X /data/weights.txt /data/out.pin -``` - -**TMT 10-plex search with mods.txt:** - -```bash -msgf-rust \ - --spectrum tmt_spectra.mzML \ - --database hsapiens.fasta \ - --output-pin out.pin \ - --mods tmt_10plex_mods.txt \ - --protocol TMT \ - --fragmentation HCD \ - --instrument QExactive -``` - -**Direct TSV output (skip Percolator):** - -```bash -msgf-rust --spectrum spectra.mzML --database db.fasta \ - --output-pin out.pin --output-tsv out.tsv -``` - -**[quantms](https://github.com/bigbio/quantms) pipeline integration:** - -Point quantms's PSM search step at `msgf-rust` and use the standard quantms post-processing. The `.pin` row format is the same; existing quantms scripts using legacy numeric flag values (`--fragmentation 3 --instrument 3 --protocol 4`) keep working without modification (see `CLI_MIGRATION.md`). - -## CLI summary - -Most-used flags (full reference in `DOCS.md` §1): - -| Flag | Purpose | Default | -|---|---|---| -| `--spectrum ` | Input mzML or MGF | (required) | -| `--database ` | Input FASTA | (required) | -| `--output-pin ` | Percolator PIN output | (required) | -| `--output-tsv ` | Optional TSV output | (off) | -| `--mods ` | mods.txt file (Cam-C + Ox-M built-in) | (off) | -| `--precursor-tol-ppm ` | Precursor mass tolerance | 20.0 | -| `--isotope-error-min/-max ` | Isotope error range | -1, 2 | -| `--charge-min/-max ` | Charge range when not in spectrum | 2, 3 | -| `--enzyme-specificity ` | NTT enforcement | fully | -| `--max-missed-cleavages ` | Missed cleavages | 1 | -| `--min/-max-length ` | Peptide length range | 6, 40 | -| `--min-peaks ` | Min peaks per spectrum to score | 10 | -| `--top-n ` | PSMs retained per spectrum | 10 | -| `--fragmentation ` | Frag method (auto-detect from mzML if `auto`) | auto | -| `--instrument ` | Instrument class | low-res | -| `--protocol ` | Search protocol | auto | -| `--param-file ` | Override bundled scoring model | (auto-pick) | -| `--threads ` | Worker threads | (logical CPUs) | - -Run `msgf-rust --help` for the auto-generated help with full descriptions. - -## Auto-detection - -For mzML inputs, msgf-rust reads the activation block of the first MS2 spectrum and selects a bundled `.param` file accordingly. The detection covers HCD/CID/ETD/UVPD activation and LowRes/HighRes/TOF/QExactive instrument classes (via mzML CV params). The bundled model is then resolved from `(fragmentation, instrument, protocol)`. MGF files have no activation metadata, so they go through the CLI defaults (which can be overridden with explicit `--fragmentation` / `--instrument` flags). Full resolution table: `DOCS.md` §4. - -## Parity vs Java MS-GF+ - -PIN output columns are bit-exact with Java MS-GF+ on the agreement bucket (same scan + same top-1 peptide) for most features. Three residual divergences exist as deferred research: `lnEValue` (num_distinct semantics), `MeanRelErrorTop7` (error-stat normalization), and the BSA charge-3 SEV gap from the deconvolution-implementation difference (`known-divergences.md` item #3, kept on the development branch). None gate cutover; aggregate 1% FDR PSM counts beat Java on all three benchmark datasets.
