The NBIA Data Retriever is a software product you can download and install so that you can download radiology images from from the TCIA Radiology Portal

If you are using Linux, you can alternatively access NBIA Data Retriever's command-line interface, which does not require the desktop environment.

In the two sample commands that follow, the -l <credential file> option is required when the manifest file contains series from restricted collections, and unnecessary when the manifest file contains series from public collections only.

The options available for the command line interface are described in the following table.

if you use the Data Retriever CLI with option  -v, -f, or -q, and want to access restricted collection(s), put these options after the user credential parameters.
