You cannot directly open a Spectra Projector window from the Mass Frontier application. You
must generate it from the Spectra Classifier module by specifying the Principal Component Analysis or the Fuzzy Clustering option for classification. You can open an unlimited number of Spectra Projector windows in the Mass Frontier application. For additional information, see Spectra Classifier Module.
You cannot alter classification results after they have been generated. To remove a spectrum
(point) from a projection plane, remove this spectrum from the input data and then launch a new classification process.
