# Simple script to extract the path of the TAG outputs of Tier0 monitoring, 
# open them and chain them in a single TChain
# Uses the pathExtract library to extract the EOS path
# Options: 
#  -r RUNNUMBER, --run RUNNUMBER : Run number
#  -s STREAM, --stream STREAM    : Stream without prefix: express, CosmicCalo, Egamma...
#  -t TAG, --tag TAG             : DAQ tag: data12_8TeV, data12_calocomm...
#  -a AMITAG, --amiTag AMITAG    : First letter of AMI tag: x->express / f->bulk
