    pub ppm_tolerance: f64,

Fields

ppm_tolerance: f64

Mass tolerance in ppm for the feature<->peptide match.

isotope_offsets: Vec<i8>

Isotope-error offsets to try. o means “koth’s mono is o neutrons heavier than the true mono”. [0] disables isotope-error search.

min_charge: u8

Skip features below this charge. Singly-charged features are usually non-peptide contaminants (and CCS predictors don’t model them).

min_isotopes: u32

Skip features built from fewer than this many isotopic peaks (0 = off). The binomial background p is set by FEATURE density x mass window, not by database size, so on an instrument with poor mass accuracy the only way to keep p in range is to search fewer, better-characterised features. On timsTOF (mass sigma ~3 ppm vs ~0.55 on Orbitrap) this is the difference between 0 and ~300 proteins: 114,659 features -> p 0.554 -> 0 proteins; gating to min_isotopes = 4 + min_combined_score = 0.85 leaves 17,587 -> p 0.206 -> 199-368 proteins at 1% honest entrapment FDP. The isotope count is the load-bearing half — min_combined_score alone (36,753 features) still yields 0. Default 0 keeps Orbitrap byte-identical.

min_combined_score: f64

Skip features whose combined_score (isotope x coelution) is below this (0 = off). Use with min_isotopes; see that field for the measurements.
