To the Editor — Tandem mass spectrometry (MS2) data provide high-confidence molecular identification of known molecules and preliminary characterization of novel, unknown molecules (unknowns). However, for databases to be an effective resource, broad chemical space coverage is necessary. Consequently, we have created METLIN (http://metlin.scripps.edu) a highly annotated and structurally diverse database of over 850,000 molecular standards. METLIN’s tandem mass spectral library numerically… 

A map of mass spectrometry-based in silico fragmentation prediction and compound identification in metabolomics

This review sheds light on individual strengths and weaknesses of these tools, and attempts to evaluate them-especially in view of lipidomics, when considering complex mixtures found in biological samples as well as mass spectrometer inter-instrument variability.

High-Throughput Non-targeted Chemical Structure Identification Using Gas-Phase Infrared Spectra.

The results suggest that matching computational with experimental IR spectra is a potentially powerful orthogonal option for adding significant high-throughput chemical structure discrimination when used with other non-targeted chemical structure identification methods.

Strategies for structure elucidation of small molecules based on LC–MS/MS data from complex biological samples

Molecular formula discovery via bottom-up MS/MS interrogation

Bottom-up tandem MS (MS/MS) interrogation to illuminate the unidentified features via accurate molecular formula annotation is presented, allowing the systematic annotation of 37 fatty acid amide molecules in human fecal data, among other applications.

Metabolite discovery through global annotation of untargeted metabolomics data

NetID applies existing metabolomic knowledge and global optimization to annotate untargeted LC-MS metabolomics data, revealing novel metabolites.

Critical assessment of chromatographic metadata in publicly available metabolomics data repositories

A unified and standardized notation for chromatographic metadata with detailed and specific description of eluents, columns and gradients is started, which will enable more standardization and automatization in future reporting.

The critical role that spectral libraries play in capturing the metabolomics community knowledge

The number of entries in publicly accessible spectral libraries has increased more than 60-fold in the past eight years to aid molecular interpretation and the role of spectral libraries in untargeted metabolomics will evolve in the near future is discussed.

Multi-metabolomics using imaging mass spectrometry and liquid chromatography-tandem mass spectrometry for spatially characterizing monoterpene indole alkaloids secreted from roots

A multi-metabolomics approach is established using imaging mass spectrometry (IMS) and liquid chromatography-tandem mass spectromaetry (LC-MS/MS) to spatially assign metabolites under laboratory conditions using agar to show that 58 nitrogen-containing metabolites are released from the roots into the agar.
