Precalibration method utilizes the knowledge that masses of peptides are in equidistant spaced clusters. The wavelength of the massesvector can be determined as described by Wool. The comparision of the experimental wavelength with the theoretical one, makes possible to find an affine function that corrects the masses. Chemical noise in the spectra may hamper the determination of mass list frequency. The package provides a function to filter chemical noise.
