[Gate-users] Problem in setting material in a volume

[Chekdob Bagdob]

Dear GATE users,

            I am using GATE 7.2 on a Ubuntu 16.04 LTS. Recently I was
reading manual for version 7.2 and when I tried this code,


>>     /gate/world/daughters/name cylindricalPET
>> /gate/world/daughters/insert cylinder
CREATED THE COMMAND /gate/systems/cylindricalPET/addAnewRsector

>>     /gate/cylindricalPET/setMaterial Water

GateMaterialDatabase.cc (l.131): GateMaterialDatabase: could not find the
definition for material 'Water' in material files

And after that Idle prompt disappears and usual terminal command prompt
comes.


   Some useful info:

   1. Geant4:: geant4.10.01.p02
   2. root:: root_v5.34 source version
   3. clhep:: 2.3.1.1

 Besides, I want to ask another question. When I googled this problem I get
various websites like

http://comments.gmane.org/gmane.comp.science.opengate.user/3939

but I can't open those websites. It just shows ArchivedAt Nothing found -
bye.
