NOMAD Laboratory is an interactive instrument, which allows sharing and publishing of scientific data (enables generation of DOI). It supports input and output files of most electronic-structure codes and provides comfortable search engine for search in uploaded files. Calculations shared via NOMAD Laboratory can be downloaded in raw and in unified archive formats. Manipulations with data stored in NOMAD can be done via GUI or programmatically via NOMAD API or OPTIMADE API.
Please note: NOMAD is not a cloud service in the strict sense. Publishing your file is irreversible (the data can then no longer be deleted) and is comparable to a scientific publication.
In order to be able to upload and to publish your calculations, create a NOMAD account.
This is the best way to prepare your upload:
1. Directories may contain further directories.
2. The names of the directories can largely be anything.
3. All files belonging to the same code run must be grouped together in one folder, if possible.
4. “One directory per calc” - rule must be adhered to.
Please make sure to compress you data to “tar.gz„ or “zip„ format before uploading. One upload is limited to 32 GB.
To upload data, log in to your NOMAD account.
Under the section “PUBLISH” will open an upload-field where the file can be added by “drag-and-drop”.
Alternatively, the file can be uploaded via terminal, using a curl command with a personal token.
Your file will be parsed and interpreted by the system to find as much metadata in the file as possible. The metadata is used to optimate the search in the user's uploads.
PLEASE NOTE: You can delete your upload only in case you have not published it yet. The published uploads cannot be deleted anymore.
Under “PUBLISH” you will find option “Your uploads”, in this section you can view and manage the file you uploaded.
Before publishing, you can manage the metadata for your datasets and add supplementary comments. To edit metadata, click the Pencil icon. A new window will open where you can add references, additional co-authors, and people you want to share the dataset with.
If the persons do not have a NOMAD account yet and therefore are not shown by the system, there is a possibility to send an invitation using the option “Invite new user” in the lower-left corner. The corresponding person will then receive a link with the invitation by e-mail.
If you are dissatisfied with your upload, you can delete it by clicking on the recycle bin icon. The already published datasets files can no longer be deleted.
As far as you decide to publish your file, you can do it using the “Publish” option. There are two possible options: with and without embargo.
Choose Publish with embargo if you want to publish your file, yet it should start to be visible to wide audience only after a certain period of time. For your co-authors and people listed in metadata, your file will become visible after publication. The maximum period for which you can set an embargo is 36 months. Thereafter, the embargo will be removed automatically. The embargo can be lifted at any time when editing metadata.
Publication without embargo makes datasets visible to all NOMAD users. If your file was published without embargo, you can no longer set an embargo for these files.
