If collected, extra datatypes (e.g., physiological or behavioural) data collected during the MRI scans need to be uploaded separately. Non-image uploads could also be technologist notes or QC .pdf files. These must be added to a subject’s session, which should be done after the DICOM files have been uploaded.

XNAT keeps the data organized under each subject’s session in resources/ and scans/. The scans/ folder holds all of the uploaded DICOM data, and the resources/ folder contains everything else. Therefore, under resources, you can create folders as nessicary:

• resources/logs – participant log sheets (.xls, .csv, .pdf, etc.)
• resources/behav – behavioural data for fMRI experiments.
• resources/physio – physiological recordings collected during the MRI protocol.

To upload data to one of these folders:

1. Navigate to the subject to which you would like to add resources, click on the session.
   
   
   
   
   
2. Click ‘Manage Files’ on the right hand bar. You should see a list of the DICOM scans under scans/ and a resources/ folder (potentially with some contents).
   
   
   
   
   
3. To create a folder: Click Add Folder. Set Level to resources and set a name for folder. Click Create.
   
   
   
   
   
4. To upload data to this folder: Click Upload Files, Level should be resources, and Folder should be the desired folder. Click ‘Choose File’ and attach the desired file file. Click Upload.
   
   
   
   
   
5. If your file was a .zip file, you will get a pop-up prompting you to unzip it if you would like, click Ok.
   
   
   
   
6. You should now see your uploaded files.
