Data preprocessing result. Spectrogram ID 2 is used as an example of data preprocessing procedure. (A) Original spectrogram without any processing. The maximum m/z ratio is 11922.91 and the minimum m/z ratio is 800. (B) Original spectrogram and adjusted baseline. (C) Noise reduction using Gaussian kernel smoothing. (D) Normalization using the area under the curve (AUC).
