Did you know that NDA offers an array of tutorials that outline the NDA submission cycle tasks in sequence? We encourage you to follow along these tutorials while navigating each step in the data submission process.
As you begin collecting data for the upcoming submission deadline, the content in the Submission Templates chapter of our Preparing and Submitting Data tutorial will guide you how to accurately fill out submission templates for your data structures.

NDA has recently revamped and simplified notifications sent to grantees!
Emails are more streamlined and contain easy to follow links on data sharing tasks and resources that can assist you in the next steps of data submission.
Please add the NIMH Data Archive email address to your "safe senders" list so that important emails don't end up in your spam folder.
If you get an email from NDA, it's important and needs action!

GUIDs, or Global Unique Identifiers, are alphanumeric codes created using the NDA GUID Tool. GUIDs provide a secure mechanism to link research participants within and across research project datasets in NDA. In some cases, the information necessary to create a GUID is not immediately available and a PseudoGUID (pGUID) may be appropriate. Once the necessary information is available, NDA requires researchers to promote pGUIDs to real GUIDs.
Know what is required to create GUIDs can save you a lot of time if you prepare in advance. All of the following information is required to create a GUID:
- First Name
- Middle Name
- Last Name
- Sex at Birth
- Date of Birth
- City/Municipality of Birth
The goal is to use real GUIDs and not pGUIDs. Promoting pGUIDs will link a pGUID to a standard GUID, essentially recognizing the two identifiers as the same individual, and is the method used to change a pGUID into a full GUID once consent is obtained.
Promoting a single pGUID behaves the same way as requesting a single GUID, except that it also requires the associated pGUID be entered as well.
After the data have been entered, and you request that the pGUID be promoted, the pGUID is sent along with the constructed hash codes to the NDA GUID Service.
The NDA GUID Tool supports promoting multiple pseudoGUIDs at once by allowing users to submit the subject source data associated with the PseudoGUID in a comma separated value (CSV) format.
Please review the NDA GUID Tool User Manual for more detailed instructions on how to complete this process!
The NIMH Data Archive (NDA) has a rolling 30-day download threshold of 20 terabytes. You should monitor how much data you’ve downloaded by opening the Download Manager Tool and clicking the ‘Settings’ tab.
Once you’ve transferred more than 20 TBs out of Amazon Web Services S3 (AWS S3) within a 30-day time period, NDA will temporarily deactivate your download abilities. During this time, you can still continue to access and process data within AWS S3. Those transfer volumes do not count against your monthly threshold.
If you want to extend your download threshold limits, please contact the NDA Help Desk and specify your download requirements, as well as the type of data you want to download. If your request is approved, NDA will temporarily extend your download threshold.
