To find the significant biomarker is very important in detecting protein patterns associated with diseases. In this study multilevel wavelet analysis is performed on high dimensional mass spectrometry data to extract the detail coefficients, which are used to detect the difference between cancer tissue and normal tissue. In order to find the key m/z values of mass spectra, wavelet detail information is reconstructed based on orthogonal wavelet detail coefficients, and genetic algorithm is further employed to select best features from the reconstructed detail information. Finally the corresponding significant m/z values of mass spectra are identified using the optimized detail features.
