About the Validation Interface

This interface allows you to upload, validate and edit CIF files before submitting them for deposition.


The process of file deposition is pretty straightforward:

  • Upload. The selected files are uploaded to the server;
  • Validation. Our scripts perform various checks to see if all of the necessary data are present in the submitted files. If a file is found to be incorrect, it can be edited in the browser window and checked again. This step can be repeated as many times as needed;
  • Deposition. The validated files can be deposited to COD. After a successful deposition COD numbers for the newly deposited structures will be displayed.

File formats

Currently we accept two types of files:

  • Plain CIF files;
  • ZIP archives that contain CIF files.
