Data Type(s): Code

Summary: This dataset includes the R workspaces, R scripts, and example data for predicting the relative retention times(RRT) and MS/MS data of methoxylated metabolites of polychlorinated biphenyls (MeO-PCBs) on a gas chromatography-tandem mass spectrometry (GC-MS/MS) system. In addition, molecular descriptors of 124 MeO-PCBs, including 99 cheminformatics-based descriptors and 6 substitution pattern-based descriptors, and the measured and predicted RRT and MS/MS data of 124 MeO-PCBs are provided in separate csv files.
