Peak Alignment of Gas Chromatography-Mass Spectrometry Data with Deep Learning [PDF]
arXiv, 2019 We present ChromAlignNet, a deep learning model for alignment of peaks in Gas Chromatography-Mass Spectrometry (GC-MS) data. In GC-MS data, a compound's retention time (RT) may not stay fixed across multiple chromatograms. To use GC-MS data for biomarker discovery requires alignment of identical analyte's RT from different samples.
