MetabNet: An R Package for Metabolic Association Analysis of High-Resolution Metabolomics Data

Front Bioeng Biotechnol. 2015 Jun 11;3:87. doi: 10.3389/fbioe.2015.00087. eCollection 2015.


Liquid-chromatography high-resolution mass spectrometry provides capability to measure >40,000 ions derived from metabolites in biologic samples. This presents challenges to confirm identities of known chemicals and delineate potential metabolic pathway associations of unidentified chemicals. We provide an R package for metabolic network analysis, MetabNet, to perform targeted metabolome-wide association study of specific metabolites to facilitate detection of their related metabolic pathways and network structures.
