XNAT is an imaging-based platform that is currently used to archive and store raw scans. All original MRI sequences (T1, DWI, fMRI, etc.) are stored in XNAT as a DICOM and niftii format. XNAT is used for the storage of storing raw scans, viewing scans, and downloading scans in preparation for pre-processing.

2. ARGUS
Virtual ARGUS is a GPU-powered Linux virtual research desktop. Frontier maintains a shared desktop that everyone within Frontier can useIn simpler terms, you can treat ARGUS as a normal point and click computer that is connected to the University network. You can use this ARGUS to run programs that have a GUI graphical aspect (e.g. fsleyes, mrview), or simply use it . Window users can also use this as a method to access Artemis via the ARGUS terminal (for windows users).mac users can already access Artemis using the terminal on their own computer).
Frontier maintains a shared desktop that everyone within Frontier can use. Multiple people can access the shared desktop at the same time.
Each supervisor (Fiona, Muireann and Ramon) also maintains a private desktop. Each private desktop can only hold one user at any one time. To gain access to these desktops, please contact the relevant supervisor.

3. Research data store (RDS)
The Research Data Store (RDS) provides a central location to securely store digital research data - information is backed up, however, data can not be processed here via ArtemisRDS is the main location where you should be storing all project information and data. All information in the RDS is backed up and securely stored. However, no heavy processing/analysis can be conducted on the RDS.
User guide:
Access: Requires dashr projectRegistration: Contact supervisor to create a dashr project.
Access: You can access RDS via terminal or by mapping a network drive. See here for more information.
4. Artemis (hpc)All
Artemis is a high-performance computing (HPC) cluster that is used for advanced computing tasks, such as modelling, batch data processing and analysis. All neuroimaging processing and analysis must be conducted on Artemis (high-performance computing). You . However, you should not store data here long term, as this space is only for active processing and is not safely secured/backed up.
User guide:
Access: Requires Registration: Contact supervisor to create a dashr project.
