Possible error in filepath lookup?

[rmastand]

I'm going through the tutorials, specifically the 2a parton level analysis. . In the same directory as the notebook, I have a file "cards", which contains proc_card_signal.dat, param_card_template,dat, and run_card_signal_large.dat.

I run the command in the 5th executable cell:

miner.run(
    sample_benchmark="sm",
    mg_directory=mg_dir,
    mg_process_directory="./mg_processes/signal1",
    proc_card_file="cards/proc_card_signal.dat",
    param_card_template_file="cards/param_card_template.dat",
    run_card_file="cards/run_card_signal_large.dat",
    log_directory="logs/signal",
    python_executable="python3",
)

which results in the error FileNotFoundError: [Errno 2] No such file or directory: './mg_processes/signal1/Cards/run_card.dat' .

So the cell is creating the folder mg_processes/signal1, but the only relevant files seem to be in './mg_processes/signal1/madminer/cards/run_card_0.dat', with the _0 appended to them.
