LipidFinder quickly distinguishes and quantifies lipid-like features from contaminants, adducts and noise in high resolution liquid chromatography/mass spectrometry (LC/MS) datasets that have been pre-aligned using SIEVE (ThermoFisher) or XCMS. An algorithm is included that optimizes analysis based on users' own data, and outputs are screened against online databases and categorized into LIPID MAPS classes.

The LIPID MAPS Tools Package uses command line Perl scripts to generate SD files containing structure and ontological data for various lipid categories. The current version supports structure generation for Fatty acyls (FA), Glycerolipids (GL), Glycerophospholipids (GP), Cardiolipins (CL), Sphingolipids (SP) and Sterols (ST). Please see our documentation for specific main and subclasses.FAStrGen.pl | GLStrGen.pl | GPStrGen.pl | CLStrGen.pl | SPStrGen.pl | STStrGen.pl

The LIPID MAPS Ontology Tools Package is a command line Perl script to generate ontology data using structure data in SD file(s).
The LIPID MAPS Mass Spectrometry Combinatorial Expansion Package includes a set of command line PHP scripts to generate tabular datasets contining species name, m/z and molecular formula for some of the main lipid categories. User-defined options include a range of chain-lengths and a choice of poitive and negative ion-types. The generated MS datasets may then be used as databases or references to aid in identification and assignment of ions in mass spectrometry experiments of lipids. The current version supports Glycerolipids (GL), Glycerophospholipids (GP), Cardiolipins (CL) and Sphingolipids (SP).
