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.

**\12. minMSMSpeaks**

Minimum MS/MS peaks within a MS/MS spectra to be used for the MetFrag calculation

**\13. PreProcessFilter**

Various filters can be performed on the potential compounds prior to predicting the in silico spectra

**\14. PostProcessFilter**

To make the output more manageble results below certain criteria can be removed from the various filters can be
performed on the potential compounds prior to predicting the in silico spectra
