[…] mass lists into a spreadsheet file using Qual-Browser 2.0 (Thermo Electron). Isotopologue peak deconvolution, assignment, natural isotope abundance stripping, and quantification were performed using MetSign software, as described previously [,]. […]


From chromatogram to analyte to metabolite. How to pick horses for courses from the massive web resources for mass spectral plant metabolomics

PMCID: 5499862
PMID: 28520864
DOI: 10.1093/gigascience/gix037

[…] ly, flexible, and extendable software constantly updated and with a set of modules covering most steps of LC-MS processing and data analysis workflow, including several option of visualization tools. MetSign [] is a MATLAB package providing tools for spectra deconvolution, metabolite putative assignment by matching m/z, and peak isotopic distribution against its own database, peak list alignment, […]


Data Dependent Peak Model Based Spectrum Deconvolution for Analysis of High Resolution LC MS Data

Anal Chem
PMCID: 3982975
PMID: 24533635
DOI: 10.1021/ac403803a

[…] After construction of the XICs, the noise in each XIC is estimated using the approaches described by Wei et al. in MetSign software. Briefly, each XIC is first segmented into several peak groups based on the continuity of scan number, and the noise level is estimated by all XIC signals, except the regions potentia […]


Computational mass spectrometry for small molecules

J Cheminform
PMCID: 3648359
PMID: 23453222
DOI: 10.1186/1758-2946-5-12

[…] und. XCMS Online[] is the web-based version of the software. AStream[] enables the detection of outliers and redundant peaks by intensity correlation and retention time, as well as isotope detection. MetSign[] provides several bioinformatics tools for raw data deconvolution, metabolite putative assignment, peak list alignment, normalization, statistical significance tests, unsupervised pattern rec […]


Chronic Alcohol Exposure Disturbs Lipid Homeostasis at the Adipose Tissue Liver Axis in Mice: Analysis of Triacylglycerols Using High Resolution Mass Spectrometry in Combination with In Vivo Metabolite Deuterium Labeling
