Getting Started with ABCD#
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.
Accessing the NDA & getting an approved DUC:#
The ABCD Repro-Nim Workshop has a guide to requesting NDA user accounts and obtaining a DUC.
For the official NIH instructions for accessing the National Data Archive (NDA), see NIH Instructions for NDA access
For an overview of the DUC and responsible data use guidelines, see: 2021 MDC ABCD Workshop.
