+MetFrag
+-------
+
+Description
+-----------
+
+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.
