[Gate-users] Gate v6.2 Source setRotationAxis

[Marc Chamberland]

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.

Marc

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.




Marc

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,

Sonoko
