Enum ThresholdMode 

pub enum ThresholdMode {
    Fixed(f32),
    AdaptiveNoise(f32),
}

Mode for computing intensity/prominence thresholds.

Global fixed thresholds are problematic because signal levels vary across the LC gradient, different m/z regions have different noise characteristics, and different samples have vastly different intensity scales.

Variants

Fixed(f32)

Fixed global threshold value (legacy behavior).

AdaptiveNoise(f32)

N × local noise estimate (computed from trace). The f32 is the sigma multiplier (e.g., 3.0 means 3× noise).

Implementations

impl ThresholdMode

pub fn fixed(value: f32) -> Self

Create a fixed threshold (for legacy compatibility).

pub fn adaptive(sigma_multiplier: f32) -> Self

Create an adaptive threshold with the given sigma multiplier.

pub fn effective(&self, noise: f32) -> f32

Compute the effective threshold given a noise estimate.
