Chemotion ELN version 1.5.0 and later allows users to transfer data to RADAR4Chem, a research data repository for chemistry data. Before you can use this feature, you need to configure the Radar integration settings in Chemotion ELN.

About RADAR4Chem

RADAR4Chem is a reliable and low-threshold publishing service for chemistry research data based on the established data repository RADAR by FIZ Karlsruhe - Leibniz Institute for Information Infrastructure. It offers free publication for any data type and format according to the FAIR principles, independent of the researcher´s institutional affiliation. Through persistent identifiers (DOI) and a guaranteed retention period of at least 25 years, the research data remain available, citable and findable long-term.


You will need a RADAR4Chem account and workspace to use this integration. Please get in touch with us, if this is not yet the case, and we will forward your request to the RADAR4Chem-Team at FIZ Karlsruhe.

Please note:

  • The RADAR4Chem offer is currently exclusively directed to researchers at publicly funded research institutions and universities in Germany.
  • Currently, the use of RADAR4Chem is limited to a maximum of 10 GB storage volume per research project.
  • Before you can publish data in RADAR4Chem, you have to agree to the RADAR4Chem License and User Instructions (PDF).

Maintaining Metadata

When preparing data for publishing via RADAR4Chem, it is important to provide the appropriate metadata information. Metadata information such as subject, rights holder, and rights are required and can be defined in the metadata editor in Chemotion ELN. Once you have entered this information, be sure to save it by clicking the "Save" button in the top-right corner of the metadata editor.


Preparing Data for Publishing

To publish data via RADAR4Chem, select the collection you want to publish and click on "Archive Publish current collection in RADAR". If the minimum required information has not yet been defined, the "Publish in RADAR" button will be disabled. In this case, click on the "Edit collection metadata" button to add the required metadata.


Publish via Radar

Once the required metadata has been added and saved, the "Publish in RADAR" button will become available. Clicking on this button will initiate the data transfer to RADAR4Chem.


RADAR4Chem Credentials: Enter your RADAR4Chem login credentials to proceed with the publication process.


If you have more than one workspace associated with your account, you will need to select the appropriate workspace before exporting the data. To do this, select the desired workspace and click on the "Export" button.


If you do not have any workspaces associated with your account, you will not be able to publish data via RADAR4Chem and you will see the following message:


Once you have clicked the "Export" button, the data will begin exporting to RADAR4Chem. A message will appear indicating that your export is uploaded to RADAR4Chem and you will be redirected once the upload is complete.


After the upload is complete, you will be redirected to the RADAR4Chem website where you can access and manage your archived data.



This integration with RADAR4Chem allows you to easily transfer and manage your chemistry research data. By following the steps outlined in this user manual, you can prepare your data for the publication and initiate the transfer to RADAR4Chem with confidence.
