BiPACE 2D—graph-based multiple alignment for comprehensive 2D gas chromatography-mass spectrometry

Nils Hoffmann, Mathias Wilhelm, Anja Doebbe, Karsten Niehaus, Jens Stoye
2013 Computer applications in the biosciences : CABIOS  
Motivation: Comprehensive 2D gas chromatography-mass spectrometry is an established method for the analysis of complex mixtures in analytical chemistry and metabolomics.  ...  Results: We describe BIPACE 2D, an automated algorithm for retention time alignment of peaks from 2D gas chromatography-mass spectrometry experiments and evaluate it on three previously published datasets  ...  ACKNOWLEDGMENTS The authors would like to thank the reviewers for their valuable comments and suggestions.  ...
