Step 2. Download the XNAT data into Artemus directory into the folder. For data in big size, it is recommended to put in to the Artemis /scratch directory.
As the example is only a small set of data (32MB), we are putting it into the home folder on the Artemis Logging node.

Step 5. Upload the result back to XNAT
[unikey@login2 ~]$ cd /home/unikey/Haofei01_MR1/scans/4-Ax_3D_T1/resources/NIFTI/
[unikey@login2 NIFTI]$ ls -ltr
