MetFrag relaunched: incorporating strategies beyond in silico fragmentation
2016
Journal of Cheminformatics
Preserved Fulltext
The in silico fragmenter MetFrag, launched in 2010, was one of the first approaches combining compound database searching and fragmentation prediction for small molecule identification from tandem mass ...
The changes to MetFrag were evaluated on the original dataset as well as a dataset of 473 merged high resolution tandem mass spectra (HR-MS/MS) and compared with another open source in silico fragmenter ...
