How can I submit my data to nmrXiv?

Do I need to register before submitting data to nmrXiv?

Yes. Registration is a prerequisite to submitting the data. Although you can submit data by logging in via Single sign-on with your GitHub or Twitter ID, this logging-in will result in registering you on nmrXiv. Alternatively, you can register via your email id. More on the registration here.

How should I structure my data in folders before submitting it to nmrXiv?

nmrXiv can structure the submitted data into datasets/studies/projects, but there is still no way to guarantee that the automatically generated structure is what the user was hoping to get. Therefore, it is recommended to have a look at the folder structuring page.

What are supported files format in nmrXiv?

nmrXiv accepts all NMR formats uploaded. However, not all of them are readable at the moment. So far, only NMRium-supported formats can be translated into spectra in nmrXiv. Those formats are jcamp-dx, jeol, Bruker folders, NMReData, and nmrium. For validation purposes, the uploaded data should have at least one readable format.

What happens to my data once submitted?

After you submit your data, it will remain private and will only be visible to you, unless you decide to make it public.

All the data uploaded to nmrXiv are stored in the S3 bucket provisioned by the University Computing Center of Friedrich-Schiller-Universität Jena and are backed up daily to the Google Cloud Storage Archive Storage with multiple regions located in the European Union.

What are public and private objects in nmrXiv?

Public/Published objects (projects, studies, and datasets) are visible and accessible to everyone (even to the non-registered users of nmrXiv). You can see all the open projects here or find them in the Projects tab in the left-hand panel of your dashboard.

Private objects (projects, studies, and datasets) are only visible and accessible to the people with whom they are shared by single sharing or in a team.


Once an object is made public, it cannot be edited, versioned, or deleted anymore, nor be made private again.

Who can use my public/published resources?

If you make your resources public (projects, studies, datasets), you are making them open for access to everyone (even to the non-registered user of nmrXiv), but you can specify rights by choosing licenses for your projects and studies (study license propagate to its datasets). Once your project is made public, you cannot edit, delete or make it private again.

How can I edit my public resources?

You cannot edit a resource (project, study, dataset) once it's made public, but you can always create another version and make changes on top of it.

How can I delete my projects, studies or dataset?

You can only delete private ones. For more details, check deletion of projects, samples, and spectra.

How can I share my resources?

You can share your resources (projects, studies, datasets) singly or in bulks within teams. For more details on sharing, please check the sharing page.

What are the available roles when sharing a resource?

You can assign roles to people with whom you share content:

  • Owner - Can read and/or update, including deleting the project, study, and dataset.
  • Collaborator - Can read and/or update the project, study, and dataset.
  • Reviewer - Can only read the project, study, and dataset.
