57  ---------------------------------------------------------
58 
59  -g
60  Input 'geometry'.
61  This option can be used to specify any of:
62  1 > A ROOT file containing a ROOT/GEANT geometry description
63  [Examples]
64  - To use the master volume from the ROOT geometry stored
65  in the laguna-lbno.root file, type:
66  '-g /some/path/laguna-lbno.root'
67  2 > A mix of target materials, each with its corresponding weight,
68  typed as a comma-separated list of nuclear PDG codes (in the
69  std PDG2006 convention: 10LZZZAAAI) with the weight fractions
70  in brackets, eg code1[fraction1],code2[fraction2],...
71  If that option is used (no detailed input geometry description)
72  then the interaction vertices are distributed in the detector
73  by the detector MC.
74  [Examples]
75  - To use a target mix of 88.9% O16 and 11.1% Hydrogen type:
76  '-g 1000080160[0.889],1000010010[0.111]'
77  -L
78  Input geometry length units, eg 'm', 'cm', 'mm', ...
79  [default: 'mm']
80  -D
81  Input geometry density units, eg 'g_cm3', 'clhep_def_density_unit',...
82  [default: 'g_cm3']
83  -t
84  Input 'top volume' for event generation.
85  The option be used to force event generation in given sub-detector.
86  [default: the 'master volume' of the input geometry]
87  You can also use the -t option to switch generation on/off at
88  multiple volumes as, for example, in:
89  `-t +Vol1-Vol2+Vol3-Vol4',
90  `-t "+Vol1 -Vol2 +Vol3 -Vol4"',
91  `-t -Vol2-Vol4+Vol1+Vol3',
92  `-t "-Vol2 -Vol4 +Vol1 +Vol3"'m
93  where:
94  "+Vol1" and "+Vol3" tells GENIE to `switch on' Vol1 and Vol3, while
95  "-Vol2" and "-Vol4" tells GENIE to `switch off' Vol2 and Vol4.
96  If the very first character is a '+', GENIE will neglect all volumes
97  except the ones explicitly turned on. Vice versa, if the very first
98  character is a `-', GENIE will keep all volumes except the ones
99  explicitly turned off (feature contributed by J.Holeczek).
100  -o
101  Sets the prefix of the output event file.
102  The output filename is built as:
103  [prefix].[run_number].[event_tree_format].[file_format]
104  The default output filename is:
105  gntp.[run_number].ghep.root
106  This cmd line arguments lets you override 'gntp'
107  --seed
108  Random number seed.
