Metabolite Annotation and Identification in R.

Metabolite annotation and identification represent one of the major bottlenecks in non-targeted metabolomics. Different levels of confidence have been defined to report results of this task, but tools often treat annotation results as equal. Here, we present example analyses based on the MetaboAnnotation R/Bioconductor package to perform annotation conforming to the Metabolomics Standard Initiative or the Schymanski scale.
