# Example script for processing of raw data
# It converts arich raw data to arichDigits and arichHits
# Using "-t 1" option the cdc tracks are also reconstructed and stored into
# the output root file (along with the arichHits).
# Using option "-a 1" only the data from events that contain reconstruced track hit
# in the is included into the output file.
# ARICHDQM module is also included, it produces "DQMhistograms.root" with some basic
# dqm histograms (using all events). You can conveniently display some of them using
# "root -l histograms.root arich/utility/scripts/plotDQM.C"
#
# NOTE: by default there is no output file made, only file with histograms from DQM
#       use option "-o filename" to make output root file with hits...
#
# run as: "basf2 arich/examples/arich_process_raw.py -- -f path2datafile.root"
# additional options:
# "-d 1" for unpacker debug info (data headers are printed, >1 raw data bits are printed)
# "-t 1" include CDC track reconstruction (reconstructed tracks are stored into output )
# "-a 1" store only data from events with track hit in arich
# "-g 1" include GDL unpacker to have TRGSummary
