Try :

   posrot1 * Set rotation matrix of x'.
   posrot2 * Set rotation matrix of y'.

Best regards,

I want to use an analytical source with a shape of a cylinder.
So I use
/gate/source/addSource cylinder
/gate/source/cylinder/gps/type Volume
/gate/source/cylinder/gps/shape Cylinder
/gate/source/cylinder/gps/radius 90 mm
/gate/source/cylinder/gps/radius0 25 mm
/gate/source/cylinder/gps/halfz 45 mm

But I don't want the axis of the cylinder to be parallel to z-axis, but 
to be parallel to y-axis.
I tried to write
/gate/source/cylinder/gps/halfy 45 mm
instead of halfz, but this command is just ignored.
Is there any possibility to turn the source, so that the axis is 
parallel to y?
I could not find anything in the UsersGuide or in the Gate-Users Archives.
I would be very glad about every help.

Kind regards,
