[Rivet] Got stuck in Rivet

[xiahou li]

Hi,

Sorry to disturb you. Recently, I am just trying to learn Rivet. My version is 2.5.2. When I want to set up the environment using source rivetenv.sh under ‘rivet/‘ path, I find that everytime I run .hepmc created by myself using ./run.sh command, the terminal just told me that RIVET_ANALYSIS_PATH and RIVET_DATA_PATH not found [1].


What should I do in order to overcome it? Where can I find the path of rivet_analysis and rivet_data?


Thanks,
Yingpu



[1]

mkfifo: cannot create fifo `fifo.hepmc': File exists
Usage: Run Rivet analyses on inputted events from file or Unix pipe

Examples:
  rivet [options] <hepmcfile> [<hepmcfile2> ...]
  my_generator -o myfifo & \ rivet [options] myfifo
  agile-runmc <genname> -n 100k -o- | rivet [options]

ENVIRONMENT:
 * RIVET_ANALYSIS_PATH: list of paths to be searched for plugin
     analysis libraries at runtime
 * RIVET_DATA_PATH: list of paths to be searched for data files


rivet: error: no such option: --process
