GNPS Tag Contribution and Supported Analyses

Warning

Pardon our dust as this is documentation is a work in progress! We also welcome your contributions.

"What are tags?"

Tags are essentially metadata about chemicals. We utilize a set of ontologies and controlled vocabulary (the same shared with ReDU). Tags reflect high-level information about your data! The tagging system in GNPS aims to generate a high-level summary of the chemical annotations provided by spectral library matching (i.e. matching of acquired MS/MS product ion scans with reference MS/MS spectra). Our goal is to reduce the amount of expert knowledge and the amount of trivial research needed to provide initial context to chemicals annotated from data run through the GNPS platform.

How to Contribute to GNPS Tags

Required Items

  1. Completed Task From a Supported GNPS Workflow.
    • Please sign-up at the GNPS homepage - link here
  2. Completed GNPS Tag Template
    • GNPS Tag Template - link here.
    • GNPS Tag Template for Large-scale Projects (>2000 chemicals annotated) - link here.
  3. Email of Completed GNPS Tag Template to GNPS Admin

Detailed Step-by-step Instructions for Completion of the GNPS Tag Template

1. Navigate to the GNPS Tag Template and Make a Personal Copy

  • GNPS Tag Template - link here.
  • Save a copy of the sample information template by going to "File - Make a copy" into a personal google drive

Info

For projects with >2000 annotations, please use the large-scale project version of the GNPS tag template - link here and complete it as described above.

2. Obtain the Annotation Information From the Supported GNPS Workflows

  • Download the annotation information from GNPS and open it in a spreadsheet program.

!!!+ info "where you can find the information to download" - Molecular Networking (Classic) - Download the "View all library hits" table from the GNPS results page. MolNetsDownload - Library Search - Download the "View all spectra hits" table from the GNPS results page. LibrarySearchDownload - Feature-based Molecular Networking - Download the "View all library hits" table from the GNPS results page. FBMNDownload

3. Setting up the GNPS Tag Template with Your Annotation Information

  • Copy and paste the entire table contents (including the header) into the "Input_GNPS_LibraryHitsTable" tab in the GNPS Tag Template.
  • If done correctly, information relevant to tagging should appear in the "GNPS Tag - Batch Tag Template" tab in columns A-D.

Info

  • All columns in light grey are for reference only and should not be modified.

4. Manual completion of the GNPS Tag Template

4.1. Open the "GNPS Tag - Batch Tag Template" tab and check the "Tag_Status1" and "Action1" columns.

  • review the information in the "Tag_Status1" column and follow the next action indicated in "Action1" column.
Tag_Status1 Action1 Description of what to do
Tags Present Check Current Tags and Add if Incomplete Check the Tags in the "Current_Tags", "Current_NCBITaxonomy", "Current_UBERON", and "Current_Lifestyle" columns. If you believe that the information is incomplete, then please add the tags you believe are missing to the "Add_Tag 1-3", "Contribute-NCBITaxonomy 1-3", "Contribute-UBERONTag 1-3", and "Contribute-LifestyleTag 1-3".
Tags Missing Add Tags Please add the tags you believe are missing to the "Add_Tag 1-3", "Contribute-NCBITaxonomy 1-3", "Contribute-UBERONTag 1-3", and "Contribute-LifestyleTag 1-3".
InChIKey-Planar Missing Add_InChIKey-Planar or Cannot_Add_InCHIKey-Planar then Check Action2 Please add the planar InChIKey to the "Add_InCHIKey-Planar" column - details on planar InChIKeys - or if an InChIKey cannot be created, then add "No InChIKey-Planar" using the dropdown in the "Cannot_Add_InChIKey-Planar" column. Check Tag_Status2 and Action2

Info

  • columns that should be ignored are colored grey.
  • a maximum of 3 tags per category can be added.
  • if additional terms are required, please submit an issue on GitHub - link here.

4.2. IF instructed to review Check Tag_Status2 and Action2 in the previous step.

  • review the information and the following actions.
Tag_Status2 Action2 Description of what to do
Tags Present Check Current Tags and Add if Incomplete Check the Tags in the "Current_Tags", "Current_NCBITaxonomy", "Current_UBERON", and "Current_Lifestyle" columns. If you believe that the information is incomplete, then please add the tags you believe are missing to the "Add_Tag 1-3", "Contribute-NCBITaxonomy 1-3", "Contribute-UBERONTag 1-3", and "Contribute-LifestyleTag 1-3".
Tags Missing Add Tags Please add the tags you believe are missing to the "Add_Tag 1-3", "Contribute-NCBITaxonomy 1-3", "Contribute-UBERONTag 1-3", and "Contribute-LifestyleTag 1-3".

Warning

  • make sure to include either a value in the "Add_InCHIKey-Planar" column or indicate that an InChIKey cannot be created in the "No InChIKey-Planar".
