This paper presents the construction of a prototype fingerprint dictionary for the identification of metabolites using simple linear combinations without a preprocessing and the usage of various algorithms for fitting curves. The identification process is reduced to comparing each point of the unknown spectrum with the value stored in the dictionary. Based on the obtained results, the concept of MR fingerprinting dictionary prototype is considered to be an alternative method for NMR signal analysis, metabolite quantification and preparing data for machine learning approach as a training set with further results comparison with fittings models.
