Downloading the Downloader Application

Get the Downloader app

Click one of the following links to download the Downloader for that operating system.

  • Windows
  • Mac
  • RPM (tested on CentOS)
    To run this file, type the following at the command prompt:
    sudo yum -v -y remove TCIADownloader.x86_64;sudo yum -y install downloader-3.2-1.x86_64.rpm
  • DEB (tested on Ubuntu)

The most convenient method of downloading is by using the Downloader. You must install the Downloader before you begin downloading. You only have to install it once to use it in future downloading sessions.

Consult the Downloader FAQ for more information about Downloader versions and usage.

If you cannot install the Downloader for any reason, you can run the Temporary Downloader (JNLP) instead.

Downloading Images Using the Downloader

When you start downloading the images you have added to the data basket, NBIA provides a list of those images in a manifest file (manifest-xxx.tcia). You must have already installed the Downloader to open this manifest file and download the images.

You can share the manifest file with collaborators so that they can download the same images that you have added to your data basket. Collaborators must also install the Downloader to open the manifest file.

If you want to share a manifest file that includes links to private image collections, you must first manually install the latest Downloader. The latest version of the Downloader controls access to private collections. In addition, your collaborators must have the same access to those private collections as you do. Otherwise, your collaborators will not be able to download images from those collections.

  1. Search for images of interest.
  2. Add those images to your data basket.
  3. Open the My Data Basket page and click Start Download.

  4. Click the manifest-xxx.tcia file.
    If you are only downloading public images, the Downloader appears, listing the items in your data basket. If you are downloading any private images, see the section about downloading private data.

    The Downloader app lists all items you selected in the data basket. You can hover your mouse over the Patient ID, Study Instance, and Series Instance columns to reveal the complete corresponding IDs. You can also resize a column by selecting and dragging the column border.

    If you do not want to download any of those items, select them in the Downloads table and then click Delete. When you remove an item from the Downloads table, it stays in your data basket.

  5. Click Browse to navigate to the destination where you want the images/annotations to be downloaded.

  6. Click Start to begin the download. You can monitor the download in the Progress column. The Status column indicates when the download for each item is complete.

    At any point in the process, you can click the Pause and Resume buttons to temporarily stop and restart the process.

    Note that files downloaded this way are not compressed. The downloaded files are stored in a child folder under the destination folder such as Collection Name > Patient ID > part of Study Date + part of Study ID + part of Study Description + last 5 digits of Study Instance UID > part of Series Number + part of Series Description + last 5 digits of Series Instance UID.

    Network Error?

    If network errors occur during large downloads, the Downloader app retries the files the number of times that your administrator has configured.

Downloading Private Data

If you are downloading any private data, you are prompted to log in.

 Once you log in, the Downloader appears.

If you do not have permission to access even one of the collections/sites to which the images you have in your manifest file, you are prompted to contact the help desk to request permission to access all of the images.
