Mass spectrometry is
an important analytical technology in nontarget analysis. The first steps in
the pipeline are signal processing and peak picking tasks. We are developing
and enhancing XCMS and related Bioconductor packages. Further characterization
uses Tandem-MS libraries, spectral searching in compound libraries with
MetFrag, and a combination thereof.
Computational Mass Spectrometry is starting to deliver powerful tools for the analysis of mass spectra. For training and validation, large gold standards are a must: “There is no data like more data” (Mercer at Arden. House, 1985). That's why we need Open Data. With modern MS instruments, we can produce large spectral libraries, but reliable annotations (and quality control !) remain a tedious process. That's why we need Computational Mass Spectrometry.
