  Usage: $progname T L [outFilePrefix [--help --skipIfComputed
             --nSeeds NSEEDS --mcTot MCTOT --mcIni MCINI --mcD MCD
             --initialSeed INITIALSEED --saveFinalConf]]

  the output file will be saved at "data_out/{{outFilePrefix}}"

  optional arguments:
    -h, --help            show this help message and exit.
    -s, --skipIfComputed  skip if the output file already exists.
    -n, --nSeeds          number of seeds which will be used for the
                          simulation.
    -m, --mcTot           number of iterations which will be performed
                          in the simulation for each seed.
    -i, --mcIni           number of iterations before the program
                          starts measuring physical properties of the
                          system.
    -d, --mcD             the program will measure the physical
                          properties when iteration % MCD == 0.
    --initialSeed         initial seed for the Monte Carlo algorithm.
    --saveFinalConf       save a file with the configuration which
                          belongs to the last Montecarlo iteration.
