*   Processing Extracted Spectra
Use the Database Manager or Spectra Classifier windows to further process a spectrum obtained from the average of scans, from scans with a subtracted background, or from component deconvolution. You can also directly search for the spectrum in a Chromatogram Processor library.
You can classify mass spectra obtained in the Chromatogram Processor using Principal Component Analysis, Neural Networks, or Fuzzy Clustering methods.
For additional information, see Organizing Spectra, Principal Component Analysis (PCA), Fuzzy Clustering, or Neural Networks Module.
