FAQs

CIF files up to 50MB in size can be deposited directly using the online deposition service available here. If the CIF you wish to upload exceeds 50MB then:

• If there are multiple structures and data_ values please split these up into individual files so there is one structure per file
• Compress (zip up) the file prior to upload

Please note that there is a limit of 50 MB per file and a limit of 100 MB for the total size of files uploaded. 

If your file is still larger than 50MB you can deposit your data by following the instructions below:

• Please contact our Deposition Team for a link and password at deposit@ccdc.cam.ac.uk
• Once you have accessed the link with the password provided, you will be presented with a file upload box
• Please add your name. This is very important because it allows us to locate your file.
• Upload your file(s)
• Please send an email to deposit@ccdc.cam.ac.uk with your name and file details. Doing this will help us give you your deposition numbers faster.
