modifinder.Spectrum.remove_small_peaks

Spectrum.remove_small_peaks(ratio_to_base_peak: float = 0.01, change_self=True)[source]

Remove peaks with intensity lower than a given ratio to the base peak.

Parameters:

  • ratio_to_base_peak (float (0, 1), default is 0.01) – The ratio to the base peak.

  • change_self (bool, default is True) – If True, the peaks with intensity lower than the given ratio will be removed in place. If False, a new Spectrum object with the peaks removed will be returned.

Returns:

  • map from old index to new index – If change_self is True, the peaks with intensity lower than the given ratio will be removed in place and a map from the old index to the new index will be returned.

  • (Spectrum, map from old index to new index) – A new Spectrum object with the peaks removed and a map from the old index to the new index.
