LipiDex: A tool for high-confidence LC-MS/MS lipid identification
LipiDex unifies all stages of LC-MS/MS lipid identification, empowering intelligent data filtering to greatly reduce manual result curation and increase identification confidence
- Create and manage custom in-silico lipid spectral libraries
- Model complex lipid MS/MS fragmentation using intuitive fragmentation templates
- Generate high-confidence MS/MS lipid identifications
- Annotate chromatographic peak tables with lipid identifications
- Automatically filter peak tables for adduct peaks, in-source fragments, and dimers
Written in Java, LipiDex accepts either .mgf or .mzXML MS/MS files and chromatographic peak tables from either Compound Discoverer or mzMine 2.
