Abstract: Metabolite identification from high throughput mass spectrometry (MS) data is highly challenging.  Current approaches use a labour intensive pipeline requiring several arbitrary thresholding steps and expert intervention.  I will present a mixture model that brings together three forms of data available from the MS output and is able to automatically group related adducts and their isotope spectra.
