Scores contribution = weighted difference between data point and average of the model; P_corr = modeled correlation or confidence; m/z = mass to charge ratio; ESI+ = Positive Electrospray Ionization mode; The position of the ions in an S plot generated from the OPLS is shown in Figure 2. ESI− = Negative Electrospray Ionization mode; Ret. Time = Retention Time.
