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.
To run the NBIA Data Retriever on CentOS, run the following sample command.
/opt/NBIADataRetriever/NBIADataRetriever --cli <location>/<manifest file name>.tcia -d <parent location>/<download directory> -l <location>/<credential file> -v –f
To run the NBIA Data Retriever on Ubuntu, run the following sample command.
/opt/nbia-data-retriever/nbia-data-retriever --cli <location>/<manifest file name>.tcia -d <parent location>/<download directory> -l <location>/<credential file> -v –f
A credential file is a text file that passes the user's credentials in the following format:
userName=YourUserName passWord=YourPassword
The parameters "userName" and "passWord" are case-sensitive.
The options available for the command line interface are described in the following table.
