Using the data provided by Sherman et al., pmc.ncbi.nlm.nih.gov, we propose the fingerprints of metabolites by means of q-Gaussian deconvolutions. Deconvolutions are obtained using Fityk software . The centers of the peaks and the parameters of the components are given in files .peaks by Fityk. The q-Gaussians are defined by Sparavigna in a script for this software. In some cases, the first-derivative spectrum has been already considered in In the method based on the first-derivative spectrum, to evaluate the peak positions, some data smoothing is necessary; here, the data are used as they are. Baseline corrections are necessary to avoid negative values of intensity.
