Auto-deconvolution and molecular networking of gas chromatography–mass spectrometry data
Nature Biotechnology, 2020 We engineered a machine learning approach, MSHub, to enable auto-deconvolution of gas chromatography–mass spectrometry (GC–MS) data. We then designed workflows to enable the community to store, process, share, annotate, compare and perform molecular ...
