Notes (temporary):

• Example:

./runPSO_exe.sh test_output_dir config/fullRun2_preUL_v02/2017/v02/BDT_step7_cate*.txt

• Before executing the command above:
  • the file PSO_input must be a symbolic-link pointing to the target input directory;
  • the latter input directory must contain a sub-directory called 2017/, which in turn must contain two files called background.root and signal.root, respectively.
