---++ Testing Mokka

This is described in the ILCSoft wiki. One can try quickly: 

<verbatim>
. /afs/phas.gla.ac.uk/data/ilc/software/ilcsoft/v01-14/init_ilcsoft.sh
cd /afs/phas.gla.ac.uk/data/ilc/software/validation/StandardConfig/current
Mokka -M ILD_o1_v05 -e ./particle.tbl bbudsc_3evt.steer
</verbatim>

---++ Changing certain detector parameters

Detector parameters are taken from (a default) database. There are many versions of the ILC detectors. One can browse this database via the [[http://www-flc.desy.de/ldcoptimization/tools/mokkamodels.php?model=ILD_o1_v05][Mokka Detector Model Database Browser]].

To change for example the number of layers in the =Hcal=, and the sensitive Si layer thickness in =Ecal=, one would add in the steering file
<verbatim>
/Mokka/init/globalModelParameter Hcal_nlayers 36
/Mokka/init/globalModelParameter Ecal_Si_thickness 0.45
</verbatim>
to the steering file and use the "-U" command line option to enable the change:
<verbatim>
Mokka -M ILD_o1_v05 -U -e ./particle.tbl my_bbudsc_3evt.steer
</verbatim>

---++ Visualisation

To visualise the detector geometry set in the steering file for example:
<verbatim>
/Mokka/init/BatchMode false
</verbatim>
and then in Geant4 prompt type
<verbatim>
/vis/open OGL
/vis/scene/create 
/vis/drawVolume
/vis/viewer/set/viewpointThetaPhi 60 45
</verbatim>
