To use the Downloader App, you must already have a manifest file that lists the files you want to download. You create the manifest file by searching the data portal of The Cancer Imaging Archive. After installing the Downloader App, double-click this manifest file to invoke the app. You cannot click the Downloader app icon alone to invoke the Downloader App.
To create a manifest file:
- Search for images of interest.
- Add those images to your data basket.
- Open the My Data Basket page and click Start Download.
A manifest file is created and downloaded to your computer.
- If you have already installed the Downloader App, double-click the manifest file to open it using the Downloader App. Click Open when your web browser prompts you to open the file.
- If you want to use this manifest file to download images more than once or download images you select on other machines, click Save at the web browser prompt. You can then double-click the saved manifest file in Windows Explorer on Windows, Finder on Mac, or File Manager on Linux to invoke the Downloader App.
