Dear gaters,

I'm trying to build the geometry of the ClearPET scanner of Brussels.
Up to the building of the cassettes everything goes ok. These cassettes 
should be repeated along  a ring repeater and the second, the fourth, 
the sixth, ... copy should be shifted along the z-axis over a distance 
of 5 mm compared to the first, third, fifth, .. copy.

So I used the following commands

/gate/cassette/repeaters/insert ring
/gate/cassette/ring/setRepeatNumber 20
/gate/cassette/ring/setModuloNumber 2
/gate/cassette/ring/setZshift1 -2.5 mm
/gate/cassette/ring/setZshift2 +2.5 mm

Unfortunately when I compile, I get the following messages:
/gate/cassette/repeaters/insert ring
/vis/scene/notifyHandlers scene-0
/gate/cassette/ring/setRepeatNumber 20
/vis/scene/notifyHandlers scene-0
/gate/cassette/ring/setModuloNumber 2
***** COMMAND NOT FOUND </gate/cassette/ring/setModuloNumber 2> *****
***** Command ignored *****
/gate/cassette/ring/setZshift1 -2.5 mm
***** COMMAND NOT FOUND </gate/cassette/ring/setZshift1 -2.5 mm> *****
***** Command ignored *****
/gate/cassette/ring/setZshift2 +2.5 mm
***** COMMAND NOT FOUND </gate/cassette/ring/setZshift2 +2.5 mm> *****
***** Command ignored *****

I do not understand since I used the exact commands as the one used in 
the usersguide page 32.
Can somebody tell me if what is wrong? Is this function out of Gate? And 
if so, how can I get this shift?
