*   Classifying Spectra
After you have selected all the groups you want to classify and chosen the classification method, you can classify the spectra groups. While the application is running the classification, you can continue to work in other Mass Frontier windows. Depending on the type of classification method you choose, the application displays the results in a Spectra Projector or a Neural Networks window.
