# python script to define the DB for b-tagging performance calibration
# Copied from the same functionality in the JetTagCalibration package
#
# This assumes:
# - a single calibration file for all channels (jet algorithms) / taggers / flavours / operating points
# - overall tag: tagname
# The ROOT file containing the calibrations should be present, with a name like: BTaggingPerformanceMyCalibV1_Cuts.root
# and it must have a GUID defined by the command: 'coolHist_setFileIdentifier.sh filename'.
#
# To run: python defineDB.py
# Results: a local file called mycool.db

# With the use of the CalibrationBroker's "ShadowFoldersAndChannels" option, there remains a single folder and a single channel.
# Everything else (notably the Jet Collections) does not affect the DB.
