SPIX: A new software package to reveal chemical reactions at trace amounts in very complex mixtures from high-resolution mass spectra dataset.

SPIX has shown its ability to reveal relevant modifications between two series of large datasets, allowing, for instance, the study of the consequences of a given event on a complex substrate. Most of all - and it is to our knowledge the only software currently available allowing this - it can reveal and monitor any kind of reaction in all types of mixture.
