    1. How to install ecat in vgate 1.0?(Juan Gao)

hello all Gate-Users:
      I have installed vGate 1.0. I installed the ECAT according to the userguide. But when I run the PET_Ecat_System.mac, it reports:COMMAND NOT FOUND</gate/output/ecat7/enable>. who can tell me why?

   Thank you for your help!

     1.  How  to  create  a  Hoffman  phantom?  (Tatsuya  Tsukahara)

Hello  dear  Gate-Users,

I  have  installed  gate_v5.0.0_p01  and  geant4.9.1.p03.
And  I'm  simulating  a  PET  system.

Now,  I'm  trying  to  create  a  Hoffman  phantom.
But  I  had  the  following  warnings:
---------------------------------------------------------------------
GateMaterialDatabase:  did  not  load  properties  table  for  material    'Vacuum'.
This  is  only  a  problem  when  OPTICAL  PHOTONS  are  transported  in  this
material.'
---------------------------------------------------------------------
This  kind  of  warning  also  appears  with:  Lung,  Brest,  Plastic.

In  addition,
---------------------------------------------------------------------
GateGeometryVoxelInterfileReader::ReadFile:  WARNING:  voxel  not  added
(material  translation  not  found);  value:  1
---------------------------------------------------------------------
And  finally,
---------------------------------------------------------------------
PANIC!  -  G4SmartVoxelHeader::BuildNodes()
                 Daughter  physical  volume  hof_brainVoxel_PVP
                 is  entirely  outside  mother  logical  volume  hof_brain_L  !!

***  G4Exception  :  InvalidSetup
           issued  by  :  G4SmartVoxelHeader::BuildNodes()
Overlapping  daughter  with  mother  volume.
-------------------------------------------------------------------------

Below  is  the  code  that  I  used  for  the  phantom  and  the  source.
I  read  the  user's  guide  but  I  didn't  understand  which  parameter  I
should  change.
Any  kind  of  hints  or  solutions  to  my  problem  are  appreciated.

Additionally  I  have  troubles  with  "point  source".
I  obtained  correct  data  with  Volume  source  but  I  couldn't  get  enough
counts  with  Point  source.
Code  for  the  point  source  is  after  Hoffman  code.
Any  kind  of  hints  or  solutions  to  this  problem  too  are  appreciated.


Thank  you  for  your  help.
