| Introducing Spectral Tree™ |
|
Mass Frontier uses spectral tree™ representation for MSn spectra. The tree structure best reflects the hierarchical spectra dependencies in tandem experiments. Mass Frontier provides a convenient graphical user interface for the management and processing of spectral trees. Spectral trees can be reconstructed from data files, or can be automatically extracted from data dependent chromatographic components or can be manually created by the user. Trees are supported by all the spectral modules except Spectra Classifier, which uses total composite spectra generated from trees. It is possible to store and search trees in libraries, to annotate every node spectrum or to create chromatographic libraries with spectral tree components. Trees can be exchanged between modules via copy/paste commands just as for single spectra. In addition, spectral trees can be exported or imported from or to Microsoft Excel® in text format. Mass Frontier uses a newly developed algorithm for the comparison of spectral trees, which is integrated in the database search procedures. Note: Most management and processing actions distinguish between a single spectrum and a tree. Therefore, when dealing with data that contains trees you should be clear in your mind whether a particular action should be applied to the entire tree or the selected single spectrum. The displayed information is also associated either with the tree or the spectrum, or both depending on the information type.
