Sketch of sequence-based encodings derived from physicochemical properties and Fourier transformation. a The numerical representations are based on the physicochemical properties of Serine (S), Glutamine (Q), Valine (V), Threonine (T), Asparagine (N) and Alanine (A). b Fourier transformation derived from the encoded peptide sequence
