Getting Started with ABCD#
ABCD access requests have changed with the release of ABCD 6.0! To work with ABCD data, you’ll need an approved Data Use Certification. Requests are now managed through the new NIH Brain Development Cohorts (NBDC) platform. A guide to data access can be found here.
Archived Instructions - Accessing the NDA & getting an approved DUC:#
To work with ABCD data, you’ll need a few things: access to the National Data Archive (NDA), and an approved Data Use Certification (DUC). As a recent update, renewing DUCs will now require creating and registering an NDA study.
The ABCD Repro-Nim Workshop has a guide to requesting NDA user accounts and obtaining a DUC.
