<HTML><BODY>Hello! I want to explain my situation. My OS is Windows7. I have installed VirtualBox-4.3.6-91406. Then I have installed vGATE 1.0 and vGATE 2.1. After that I have tried to launch examples in these versions of vGATE. All examples don't work. The most common mistakes: 1. Can not open a macro file <Verbose.mac>; 2. Could not find material database file 'GateMaterials.db'; 3. Can not open a macro file <Visu.mac>; 4. Can not open Materials.xml. Several times I have seen such mistake: Can not find material "Water" in GateMaterials.db (Although record with all necessary information about this material is written in GateMaterials.db). I launch examples in Terminal in the following manner: gate@vgate:~$ Gate /home/gate/Progs/Gate/gate_v6.2/examples/example_Radiotherapy/example1/mac/main.mac (It is one of the examples, main.mac is name of general macros in this case). Below I give a response to my attempt to launch main.mac in Terminal in vGATE 2.1 (It is example1 in the folder example_Radiotherapy): gate@vgate:~$ Gate /home/gate/Progs/Gate/gate_v6.2/examples/example_Radiotherapy/example1/mac/main.mac [G4] [G4] ************************************************************* [G4] Geant4 version Name: geant4-09-05-patch-01 (20-March-2012) [G4] Copyright : Geant4 Collaboration [G4] Reference : NIM A 506 (2003), 250-303 [G4] WWW : http://cern.ch/geant4 [G4] ************************************************************* [G4] [Core-0] Initialization of geometry [Core-0] Initialization of physics [Core-0] Initialization of actors [Core-0] [Core-0] ********************************************************************** [Core-0] GATE version name: gate_v6.2 [Core-0] Copyright : OpenGATE Collaboration [Core-0] Reference : Phys.

I tried to launch it with no changes and with my some corrections but in both cases it doesn't work (I didn't forget to allow executing file as program and I wrote in the name an extension .mac).
