# runmerpp
#
# This scripts is used to run merpp on a full Period of data. It will run merpp
# on the raw-data file. Then it will update the root file by merpping in the CC
# and CACO data.
# As for some rawdata files no CaCo data files exist (due to DAQ restarting a run)
# we need to use the previous CaCo file. This will add to much dc-current infos
# to the merpped file, but will gaurantee that the right dc-currents are always
# available.
#
# TODO:
#  Due to problems with the DB the automatic DB update option is still disabled.
