After understanding the general function of each system, you will need to understand how to use these systems for a neuroimaging project.
*You can skip the first 3 steps if you are comfortable with transferring files from XNAT directly to Artemis using command line.
1. Download files from XNAT to local computerRDS/ARGUSArtemis
Raw image files (DICOM and niftii) of FRONTIER scans are currently indexed on XNAT. You will need to search and select the relevant scans and download them into . You should not download them onto your local computer or ARGUS. If you do download into ARGUS, please delete these scans as soon as they are uploaded to the RDS (step 2).
2. Transfer files from local computer/ARGUS to RDS/Artemis
After downloading the scans onto your local computer or ARGUS, you will need to transfer them to RDS (secure storage). Remember to delete the scans from your local computer/ARGUS once this step has been completed. You can access both the RDS and Artemis scratch folder using the HPC.
Transferring between local computer and HPC.
On the HPC, there are two main folder locations to be aware of:
/scratch : used for processing/analysis
/rds : used for storage
3. Transfer files from RDS to , please instead follow the instructions found in the XNAT guide for downloading.
2. Transferring data between RDS and Artemis (/scratch)
Scans need to be copied into /scratch for processing/analysis . Note: but Artemis is NOT to be used for long term storage (as it is not secure/backed up). For long term storage, files should be saved to RDS.
Transferring data between HPC and RDS using dtq.
This method can also be used to transfer files between 2 RDS projects.
