Spectra data frame |
The alignment of peaks is an alternative to binning the spectrum to account for peak shifts. A peak detection graphical application (Preprocessing / Peak Detection) has been developed to control the ''msc.peaks.find'' function from caMassClass library. The graphical application adjusts the signal-to-noise ratio and the threshold criterion in the peak's detection process and it returns a data frame with the positions and intensities of the detected peaks. Launched with the GUI. Beta version.
