我们设计了一种机器学习方法MSHub,以实现气相色谱-质谱(GC-MS)数据的自动去卷积。然后,我们设计了工作流程,使社区能够在全球天然产物社会(GNPS)分子网络分析平台内存储,处理,共享,注释,比较和执行GC-MS数据的分子网络。MSHub/GNPS通过无监督非负矩阵分解对化合物碎片模式进行自动去卷积,并量化样品间碎片模式的重现性。
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 networking of GC-MS data within the Global Natural Product Social (GNPS) Molecular Networking analysis platform. MSHub/GNPS performs auto-deconvolution of compound fragmentation patterns via unsupervised non-negative matrix factorization and quantifies the reproducibility of fragmentation patterns across samples.
