matchms.filtering.peak_processing.select_by_intensity module

matchms.filtering.peak_processing.select_by_intensity.select_by_intensity(spectrum_in: Spectrum, intensity_from: float = 10.0, intensity_to: float = 200.0, clone: bool | None = True) → Spectrum | None[source]

Keep only peaks within set intensity range (keep if intensity_from >= intensity >= intensity_to). In most cases it is adviced to use select_by_relative_intensity() function instead.

Parameters:

  • spectrum_in – Input spectrum.

  • intensity_from – Set lower threshold for peak intensity. Default is 10.0.

  • intensity_to – Set upper threshold for peak intensity. Default is 200.0.

  • clone – Optionally clone the Spectrum.

Returns:

Spectrum with peaks within the specified intensity range, or None if not present.

Return type:

Spectrum or None
