• SIMAT is a tool for analysis of GC-MS data acquired in SIM mode. The tool provides several functions to import raw GC-SIM-MS data and standard format mass spectral libraries. It also provides guidance for fragment selection before running the targeted experiment in SIM mode by using optimization. This is done by considering overlapping peaks from a library provided by the user. Other functionalities include retention index calibration to improve target identification and plotting EICs of individual peaks in specific runs which can be used for visual assessment.

    • MetaboSearch is a tool for metabolite identification by searching against four databases: Human Metabolome DataBase (HMDB), Madison Metabolomics Consortium Database (MMCD), METLIN Metabolomics Database, and LIPID Metabolites and Pathways Strategy (LIPID MAPS). The search results from these databases are integrated into a uniformly and non-redundant format based on IUPAC International Chemical Identifier (InChI) key.
