XNAT data syncing

Scan data in XNAT can be mirrored using a local XNAT or copied using the REST API.

One way to use the API is using either python xnat or xnatpy library.

For rsync from MRRC MR Data Filesystem (gyrus) or fw download using Flywheel comparable scripts:.

• An example using import xnat from MC is on github.
• Alternatively, a script to mirror the dcmtk storescp DICOM listener file and path pattern written to scan_data/ can be found on https://github.com/NPACore/xnat-hpc/tree/main/misc/xnat_sync_raw.py.
