Overview
The Yale Test-Retest Dataset (Yale TRT) comprises twelve extensively-sampled healthy individuals (144 min data each across two identically-configured scanners) and was collected with the purpose of assessing the intrinsic organization of the human brain at rest. Altogether, 144 min of functional data was collected for each subject (4 sessions/subject × 6 runs/session × 6 min/run). At each session for each subject, six functional scans and three anatomical scans (MPRAGE, FLASH, and SPACE) were acquired. The complete dataset includes:
The complete dataset includes:
- 288 functional scans (12 subjects x 4 sessions/subject x 6 runs/session)
- 136 anatomical scans (12 subjects x 4 sessions/subject x 3 scans/session - 8 missing scans)
- missing SPACE scans: sub-032410 sessions 3-4, sub-032411 sessions 3-4, sub-032412 sessions 1-4

Experimental Protocol
Subjects were instructed to keep their eyes open, stay awake, remain still, try to relax, and try not to think about anything in particular. No visual stimulation was provided; subjects were shown a black screen.

Data are also available for download as files in an Amazon Web Services S3 bucket.
Each file in the S3 bucket can only be accessed using HTTP (i.e., no ftp or scp ). You can obtain a URL for each desired file and then download it using an HTTP client such as a web browser, wget, or curl. Each file can only be accessed using its literal name - wildcards (i.e. "*") will not work.
There are file transfer programs that can handle S3 natively and will allow you to navigate through the data using a file browser. Cyberduck is one such program that works with Windows and Mac OS X (New Cyberduck version might not work, please try version 5.03.). Cyberduck also has a command line version that works with Windows, Mac OS X, and Linux. Instructions for using the Cyberduck program are as follows:
- Open Cyberduck and click on Open Connection.
- Set the application protocol in the dropdown menu to S3 (Amazon Simple Storage Service).
- Set the server to s3.amazonaws.com.
- Check the box labelled Anonymous Login.
- Expand the More Options tab and set Path to fcp-indi/data/Projects/INDI/YALE/folder/test_retest.
- Click Connect.
