A method for automatically identifying peaks in mass spectral data includes estimating m/z-dependent levels of background and noise, detecting all peaks with signal-to-noise ratio above a user-specified threshold, and compiling a list of all detected peaks including their m/z positions and intensities. The method can be extended to automatically detect monoisotopic peaks, to detect monoisotopic peaks in the presence of chemical noise, and to detect resolved isotopic clusters at high mass. |
