There you will find a box called Import Data Share. From the Select Input Files popup, you will be a shares files tab. We can select our own files to analyze.Īlternatively, we can import an existing public dataset if we know the dataset accession ( Browse Datasets). Select files for analysis by first clicking "Select Input Files". This title will be helpful when you retrieve your data after the workflow is completed. Provide a detailed title for your molecular network. This will bring you to the workflow input to start networking. Running Molecular Networking ¶ Molecular Networking Workflow Selection ¶įrom the main GNPS page, click the "Create Molecular Network" button. To convert your file to the appropriate formats, check out our documentation. Molecular networking supports mzXML, mzML, and mgf file formats. Mass Spectrometry data files (required).The follow data is can be put into molecular networking. This map of all related molecules is visualized as a global molecular network.įor more information about Molecular Networking check out the GNPS publication from 2016. as abundance, origin of product, biochemical activity, or hydrophobicity, which can be reflected in a node’s size or color. Nodes can be supplemented with metadata, including dereplication matches or information that is provided by the user, e.g. The visualization of molecular networks in GNPS represents each spectrum as a node, and spectrum-to-spectrum alignments as edges (connections) between nodes. This visualization approach can detect sets of spectra from related molecules (molecular networks), even when the spectra themselves are not matched to any known compounds. Molecular networks are visual displays of the chemical space present in tandem mass spectrometry (MS/MS) experiments.
