MetFrag MetLogoCube Green

Overview:
MetFrag is a freely available software for the annotation of high precision tandem mass spectra of metabolites which is a first and critical step for the identification of a molecule's structure. Candidate molecules of different databases are fragmented in silico and matched against mass to charge values. A score calculated using the fragment peak matches gives hints to the quality of the candidate spectrum assignment

Availability:
MetFrag can be easily used via the web tool (https://ipb-halle.github.io/MetFrag/projects/metfragweb/). For high-troughput data processing the commandline version should be most convenient as well as the R-package for users versed in the R programming language.
