[Gate-users] Problem with Regular navigation algorithm developed by Mr David Sarrut

[Konstantinos P. Chatzipapas, MSc]

Hello,
Is this what you have in your code:
/gate  /_phantom/geometry/setImage            ../data/m000-sorti16bit_golem.h33

or you have it correct like this:/gate/_phantom/geometry/setImage            ../data/m000-sorti16bit_golem.h33

 dear gate users from few weeks I tray to use a Regular navigation algorithm developed by Mr David Sarrut (Region-oriented CT image representation for reducing computingtime of Monte Carlo simulations 2008), as follow:
/gate/world/daughters/name                    _phantom
/gate/world/daughters/insert                     ImageRegionalizedVolume
/gate  /_phantom/geometry/setImage            ../data/m000-sorti16bit_golem.h33
/gate/_phantom/geometry/setRangeToMaterialFile        ../data/range_geo.dat  


 but it does not work. It gives this error: 
Core-0] Initialization of geometry
GateImageRegionalizedVolume.cc (l.195): ImageRegionalized Volume <golem_phantom> : No distance map provided, the navigation could not be optimized.
Please use /gate/golem_phantom/geometry/buildAndDumpDistanceTransfo dmap.mhd
to generate the dmap and then, /gate/patient/geometry/distanceMap dmap.mhd to use it. 

please, if someone already used this algorithm, tell me how can I solve this problem.thank you._______________________________________________
