 There are optional command line arguments for gprMax:

-``-n``        integer used to specify the number of times to run the input file. This option can be used to run a series of models, e.g. to create a B-scan with 60 traces: ``(gprMax)$ python -m gprMax user_models/cylinder_Bscan_2D.in -n 60``
-``-restart``  integer used to specify the starting number for a model. It would typically be used to restart a series of models from a specific model number, with the ``-n`` argument, e.g. to restart from A-scan 30 when creating a B-scan with 60 traces: ``(gprMax)$ python -m gprMax user_models/cylinder_Bscan_2D.in -n 15 -restart 45``

 * ``-n`` is used along with a integer number to specify the number of times to run the input file. This option can be used to run a series of models, e.g. to create a B-scan with 60 traces: ``(gprMax)$ python -m gprMax user_models/cylinder_Bscan_2D.in -n 60``
