If you access this page from the project level, you will have access to all subjects within the project, and all their experiments (Image 6). If you access it from a subject page, you will have access to all experiments for that subject. If you load it from an experiment page, you will only have access to that experiments’ data (Image 7).

There are multiple ways you can download your data from this page, you should use either:
- Download via Desktop Client – This requires the XNAT Desktop Client to be installed (it is best suited for Windows and Mac devices – see the install guide for details).
- ZIP download – Your selected data will be downloaded via the browser in a .zip file.
Once you have selected the data you want, and the method you want to use to download it, you can click the Submit button to start the process (Image 7).
Alternative Download Method
On an experiment page scans can also be selected for downloading. Check the boxes to the left of the scan ID's to select what to include, and then use the Download button above them to start a .zip download (Image 8).
