Description

Initialization should issue a warning if there are multiple dataPar*.json in /derivatives/ExploreASL, and print which one it is using.
Or should it only issue the warning and request to move the other dataPar file out?

Testing

/External/TestDataSet has this, when you skip the import and run the processing only.

Release

Issue a warning when multiple dataPar*.json or studyPar*.json or sourcestructure*.json are present.
