    摘要: Methods and apparatuses are disclosed that model the lineshapes of mass spectrometry data. Ions can be modeled with an initial distribution that models molecules as having multiple positions and/or energies prior to traveling in the mass spectrometer. These initial distributions can be pushed forward by time of flight functions. Fitting can be performed between the modeled lineshapes and empirical data. Filtering can greatly reduce dimensions of the empirical data, remove noise, compress the data, recover lost and/or damaged data.
