[Gate-users] Cubic source

[e12005820]

Dear Julia and Francisco,
many thanks for your help! It seems it was sufficient to ignore the 
angles lines:

/gate/source/NAME/gps/pos/type Volume
/gate/source/NAME/gps/shape Para
/gate/source/NAME/gps/halfx 0.05 cm
/gate/source/NAME/gps/halfy 0.05 cm
/gate/source/NAME/gps/halfz 0.05 cm
#/gate/source/NAME/gps/paralp 90. deg
#/gate/source/NAME/gps/parthe 90. deg
#/gate/source/NAME/gps/parphi 90. deg
/gate/source/NAME/gps/centre 0.0 0.0 0.0 cm
/gate/source/NAME/visualize 1000 red
/gate/source/NAME/gps/angtype iso

Thank you again,
Daria
