OAI Tutorials

A variety of tutorials and instructional pages are available throughout the OAI and NDA websites to assist with specific tasks related to using OAI data. All of these tutorials can be found on this page.

Getting Access to OAI

Learn how to create an NDA account and register for access to OAI, and navigate the OAI and NDA websites.

Downloading SAS/ASCII Datasets

Learn how to use the OAI website to download the OAI data set.

Getting OAI Images

Learn how to get OAI images in ZIP files by timepoint.

Querying NDA-OAI Data

Learn how to use the tools available on the NDA website to query and filter reformatted OAI clincial data, and imaging metadata. DICOM images are available in GZIP format at the series level.
