[Gate-users] Gate v6.2 Source setRotationAxis

[Sonoko Nakano]

Hi Marc,

Thank you for the reply.

When I visualized the source, yes, it was NOT rotated, but the volume was rotated as I expected.
But as you mentioned, I thought that it was just a visualization problem, so I ran the simulation.

But when I reconstructed the source object, I noticed that the source was NOT rotated.

Thank you,


Sonoko

Hi Sonoko, 


This problems sounds familiar to me. Have you actually run your simulation? Try it out quickly with a back-to-back source and then check that your photons are emitted from where you think the source should be. 


I vaguely remember that sources did not show their updated position in the viewer, but maybe I'm just making it up. In any case, a short simulation should tell you if your source is placed correctly or not.

Hello Gate users, 

I tried to attach the source to a volume and rotate the volume. But the source is not rotated. 
Can someone help me?

When I view the volume (called Phantom1), it is rotated. 
But when I view the source, it is not rotated. 

Thank you, 

Sonoko

Someone can correct me if I'm wrong, but I don't think you can use these commands with a source. 


You have to use the Geant4 General Particle Source (gps) commands to position a source. 


See the Geant4 gps user's manual here: http://reat.space.qinetiq.com/gps/new_gps_sum_files/gps_sum.htm 




But I believe a simpler alternative is to attach the source to a volume and place (or move) the volume as you wish.

Hello Gate users, 

My computer is MacBook Pro(Mac OSX), and I am using gate v6.2. 

When I use /gate/source/[source name]/setRotationAxis 1 0 0 
/gate/source/[source name]/setRotationAngle 90 deg 

I got an error message: 

***** COMMAND NOT FOUND </gate/source/[source name]/setRotationAxis 1 0 0 > ***** 

Can someone help me? 

Thank you,
