Questions about Downloading Images

Questions about Downloading Images
1. How do I download images in JPEG, TIFF, or BMP rather than DICOM format?
You can download items you add during the current work session. Before you download items you must download and then install the NBIA Data Retriever.
You select items to download by first searching for them in TCIA and then adding them to your cart.
The legacy Download Manager permits downloading of DICOM images only. To capture a large number of images, download them in DICOM and then reference the websites below for assistance with utilities that will convert DICOM images to other formats.
To download only a single image (or a handful of images one at a time):
- In the NBIA application, choose a study and series, then Show Images;
- Right-click over the image and Save Picture As .(jpeg).
2. How do I download annotated image files?
The .XML files are in the series folder since they are related to the images in that series. You can find the annotated files by viewing the list of files in a given folder.
3. What Java version is required for Download Manager?
Java version 6 or higher of the Java Runtime Environment (JRE) must be installed to be able to open the Download Manager. See Download Manager for more information.
4. What if I receive an error message from Download Manager or Download Manager hangs?
The number of series that can be downloaded using Download Manager is dependent on several factors: average image size, RAM on your computer, free disk space on your computer, network speed, and Java limitations. If you experience issues or errors associated with the download, reduce the number of series in your basket and try again.
If you never even see the Download Manager GUI, and Java reports that the Download Manager failed to launch, you may be running an old version of Java, and/or your Java application cache may be stale and needs to be cleared. See Clearing the Java Application Cache for instructions on how to clear the cache.
In some cases, the first attempt to run Download Manager on a computer might fail. Please simple retry launching the download manager (i.e., click on the "Download Manager" link on the shopping cart page). If the error persists, please contact TCIA's helpdesk at help@cancerimagingarchive.net , letting them know what computer, operating system version of Java that you are using. You can find instructions for determining this information at this link (click here).
5. I am behind a proxy server, will Download Manager work?
Accessing TCIA’s Download Manager directly through a proxy server is currently not supported. If your only access to the Internet is through a proxy server, our current recommendation is to ask your IT Department to allow your workstation to bypass the proxy server for direct access to https://public.cancerimagingarchive.net/ncia.
Java may be configured to utilize proxy settings; however, the developers of NBIA have not tested whether Download Manager correctly handles such settings.
6. Does Download Manager work with any browser?
Theoretically, yes. However, we principally test with Firefox, Chrome, and Internet Explorer. We also test with Safari (the default browser on most Macs), and it did work up to version delivered on Mac OS X version 10.8.3 (Mountain Lion). After 10.8.3, Safari will silently download the JNLP file used to launch the Download Manager, but will not automatically start the Download Manager program. Safari does not give the user any warning, so to the casual user it appears that the Download Manager link is broken. One has to go to the Downloads folder, find the JNLP file just downloaded, and then command | control | right click the JNLP file and select "Run" from the pop-up context menu to start the Download Manager.
Some browsers on some operating systems do not have our Certificate Authority in their list of trusted root Certificate Authorities. In these cases, the browser may present a warning about not trusting the connection to the web site. You may still be able to download images by clicking on the "Continue" or similar button.
7. Are there operating system requirements for Download Manager?
In theory, the Download Manager, being Java based, will work on any operating system. However, the Mac OS X operating system has been imposing additional security requirements on Java Web Start programs, such as the Download Manager, which make it difficult to run them without having administrative access to the Mac. In particular, the Gatekeeper function in 10.8.4 (Mountain Lion) and later versions of Mac OS X by default blocks starting third party programs that have not been either obtained from the Apple App store, or that have not been signed with an Apple Developer ID. This includes, naturally, Java Web Start programs such as the Download Manager. To get around this restriction, one can either change the default Gatekeeper setting, found in the Security tab of Apple System Preferences, to allow the running of 3rd party applications, or download the JNLP file used to launch the Download Manager, and then command | control | right click the JNLP file and select "Run" from the pop-up context menu. Note that either method requires either having administrative access to the Mac OS, or knowing the username/password of an administrator account, since the Mac will prompt for this information.
8. What if I am unable to download images through Download Manager and receive an error message in the status bar?
Our support team needs the following information to perform additional troubleshooting:
1. A screen capture of the error message.
2. A screen capture of the Java console (you may need to enable viewing the Java console using the Control Panel > Java Control Panel > Advanced > Settings: Java Console > Show Console).
3. Operating system and version.
- Windows XP: Start > Control Panel > System > General tab.
- Windows 7: Start > Control Panel > System and Security > System.
4. Browser and version.
- Internet Explorer: From the menu bar, select Help > About Internet Explorer.
9. How many series can Download Manager download from a single shopping cart?
Theoretically, there is no maximum number of series that Java allows Download Manager to hold in a single shopping cart. However, it is not practical to download more than around 3500 series at one time. The number of series in your basket will display on the left navigator at the top under My Data Basket > View Contents.
10. Where does Download Manager save my images?
When downloading images the default destination location for Windows devices is a path that is hidden by default which makes it hard to locate after the download completes. We suggest clicking the "Browse" button and selecting a more convenient destination for your data.
