> Hi Gaters,
>
> I'm interested in tilting pinholes toward a common volume in a 
> multi-pinhole aperture. To do this in GATE, I'm appropriately 
> translating and rotating two back-to-back cones to form one pinhole.
> I'm running into problems when I try to perform multiple rotations, 
> first say around the y-axis to get the first cone oriented in the 
> collimator plate, and second around the z axis to tilt the cone 
> towards the FOV. Only the last rotation actually occurs, starting from 
> the initial configuration of the volume.
>
> This same issue has been raised before 
> (http://lists.healthgrid.org/archives/gate-users/2006-December/001613.html), 
> but I could not find any responses.
>
> Any ideas?
>
> Thanks,
