Zusammenfassung:A method for deconvoluting measured mass spectrometry data, the method comprising: receiving measured mass spectrometry data representing at least two molecular moieties each having a respective isotopic pattern, wherein at least two of said isotopic patterns overlap; iteratively filling a set of mass channels to produce an approximated version of the mass spectrometry data, said iterative fillingcomprising a number of iterations, each iteration comprising filling one or more of the mass channels with a chunk of intensity data according to the isotopic pattern of a respective one of the two or more molecular moieties selected for said iteration; terminating said iterative filling when a fitness criterion is met indicating a fit of the approximated version of the mass spectrometry data tothe measured mass spectrometry data; and determining the amount of each molecular moiety that produced the measured mass spectrometry data based on the total amount of fills according to the respective isotopic pattern of said
