Gate 9.0 version putting circulare source for PET imaging

Continuing the discussion from GATE Toolkit & Medical applications:

Does anybody know how to create a circular source 10 cm from the center in Gate version 9.0?

I used this, but I got an error.

/gate/source/Name2/gps/pos/type Point
/gate/source/Name2/gps/pos/centre 11.5 0.0 2.0 cm
/gate/source/Name2/gps/pos/shape Circle
/gate/source/Name2/gps/pos/radius 0.0 cm

It would be best to direct this to the GATE developers and mailing list here:
