Feature-based molecular networking (FBMN):an advanced method for molecular networking that provides accurate ion abundance for statistical analysis and provides support for isomer resolution or ion mobility. FBMN requires the processing of the LC-MS/MS with tools such as MZmine or XCMS, prior to ...
其中,FBMN(Feature Based Molecular Networking)是GNPS中的一种操作流程,用于将质谱数据进行特征提取,并通过网络图谱的方式展示不同样本之间的相似性和差异性。本文将详细介绍FBMN操作流程的步骤和原理。 一、数据预处理 在进行FBMN操作之前,首先需要对原始质谱数据进行预处理。这一步骤主要包括峰提取、去噪、归一化和...
FMBN还提供了带有离子淌度的分子网络,目前使用FMBN积分的淌度数据可以用MetaboScape、MSdial、Progenesis QI处理。详细的FMBN使用教程请看网站https://ccms-ucsd.github.io/GNPSDocumentation/featurebasedmolecularnetworking/. 参考文献 Nothias, L.F.; Petras, D.,et al. Feature-based molecular networking in the ...
Molecular networking has become a key method to visualize and annotate the chemical space in non-targeted mass spectrometry data. We present feature-based molecular networking (FBMN) as an analysis method in the Global Natural Products Social Molecular N

A window for visualization will open. You can explore your data changing the feature in the bottom right. You can also set different parameters in the right window, such as the size of the spot or the color of mapping. There, you will also find some more examples to explore. ...
The profiles of its chemical compounds were examined using a Global Natural Products Social (GNPS)-based molecular networking analysis. Guided by this, we successfully isolated and characterized 11 compounds from G. biloba fruit, including (E)-coniferin (1), syringin (2), 4-hydroxybenzoic acid 4...
GNPS Molecular Networking是一种可视化工具，用于展示串联质谱（MS/MS）实验中的化学空间。它能检测相关分子集合，即使这些谱图与已知化合物不匹配也能识别。在GNPS中，每个谱图被表示为一个节点，谱图之间的相关性通过节点之间的连线（边缘）呈现。节点可以附加元数据，如 dereplication匹配信息，用户提供的...
