Detailed Description

The SpectrumAddition is used to add up individual spectra.

It uses the given sampling rate to resample the spectra in m/z domain and then add them up. This may lead to a certain inaccuracy, especially if a inappropriate resampling rate is chosen.

addUpSpectra() [1/3]

static OpenSwath::SpectrumPtr addUpSpectra ( const SpectrumSequence &  all_spectra, const RangeMobility &  im_range, double  sampling_rate, bool  filter_zeros  )
