Dataset for Figure 1 (file ‘Dataset for Figure 1.xlsx’).</b>The file is in the Microsoft Excel program format and includes data for Figure 1.<b> </b><b>6. Dataset for Figure 3 (file ‘Dataset data for Figure 3.xlsx’).</b>The file is in the Microsoft Excel program format and includes data for Figure 3.<b></b><b> </b><b>7.</b> <b>Source code for the SantoOmics algorithm and the data to run it.</b> The source code is presented as a Matlab script (file <b>‘SantaOmics.m’</b>). Data are presented as a saved Matlab workspace (file <b>‘workspace.mat’</b>). To run the SantaOmics algorithm, the workspace should be loaded in the Matlab program, and ‘SantaOmics.m’ should be evaluated in the Matlab environment. Mass peak intensities of the initial mass spectra (presented in variable ‘intensities’; n = 15) should be standardized and written as variable ‘standardized_intensities’. Depending on the power of the computer, the algorithm may take from several to tens of minutes to complete.
