Accessing Data
How to access data in XNAT
Calpendo Integration
MEG and MRI Projects in Calpendo will be mirrored in XNAT (provided data from the project has been uploaded to XNAT). The system will attempt to assign a PI, project owner, and project users to the XNAT project based on the details it finds in Calpendo. This sync happens once an hour, so any changes made in Calpendo should be reflected in XNAT within 1-2 hours. Provided you are listed in Calpendo as a user of a project, you should have access to all that projects’ data in XNAT.
Finding your data in XNAT
From the XNAT homepage, on the left you will see a list of projects you have access to. On the right, you will see an activity feed for recently uploaded or modified data you have access to, with quick links to take you directly to them (Image 1). Clicking on a project name will take you to the project page.

On a project page you will see metadata for the project taken from Calpendo, along with a list of subjects (Image 2). Clicking on a subject name will take you to that subjects’ page.

On a subject page you will see a list of all imaging sessions for that subject (Image 3). You will see a mix of the terms “Experiment” and “Session”, in XNAT they are interchangeable. Clicking on an experiment will take you to that experiments’ page.

On an experiment page you will see a list of the individual scans in the session, with descriptions and file counts.
