A python script that re-runs an updated anonymisation script on all MR sessions in an XNAT project

anonymizeall.py

# Renames every MR experiment, thus kicking off the anonymisation script.
# see https://groups.google.com/d/msg/xnat_discussion/vvLyLvyo2uQ/yMPHgkrOEwAJ
# used in XNAT 1.6.5
# also see https://groups.google.com/d/msg/xnat_discussion/fBI33j36D3Y/VEwh-HWez70J for discussion about changing experiment label
import xnat # see https://xnat.readthedocs.io/en/latest/
