The data repository users can download selected datasets from the repository to their local machines. The Data Download tool (available via the Data Download module) assists users in this task. The tool runs locally as a Java Web Start application on a user's computer (requires the Java runtime environment).
System requirements
The most recent version of Java Runtime Environment (JRE) (6 or 7) is required in order to run the Imaging Data Submission and Validation module.
