[Gate-users] No coincidences when using generic repeater in PET

[강한규]

Dear Zhengzhi, and Christian,
 
As you already know, Christian (pommranz at astro.uni-tuebingen.de) shared the git patch file to solve the coincidence output issue. 
http://lists.opengatecollaboration.org/pipermail/gate-users/2019-February/010729.html
 
I have also succeeded in acquiring coincidence output using generic repeater inPETscanner system with the patch file shared by Christian.
Below is an example of the detector arrangement with genericRepeater.
Thanks Christian for your great contribution~!
 
  
Here is a brief manual how to apply the git patch in GATEv8.2.
===========================================================================================================================
Problem: No coincidence in the "PETscanner" when genericRepeater was used.
Solution: Modify the GATEv8.2 source code using a git patch file and re-compile.

STEP1> Download the git patch file in the mailing list.
Filename: coincidences_for_generic_repeater.patch
 
STEP2> Apply the git patch file.
>cd /home/kanghg2/program/Gate-8.2
>git apply --ignore-space-change --ignore-whitespace coincidences_for_generic_repeater.patch
 
STEP3> Re-compile GATEv8.2
>cd /home/kanghg2/program/Gate-8.2-build
>ccmake ../Gate-8.2
[c] configure
[g] generate
 
>make
 
STEP4> Run the GATE PETscanner with genericRepeater.
Now coincidence output will be generated!
===========================================================================================================================
 
Hopefully, you will be able to obtain coincidence output with genericRepeater.

Dear GATE community members, 
 
I looked at previous GATE correspondence, it looks there has been an issue with coincidence sorter when using along with generic repeater. I am using vGATE8.2, it still exists. 
 
Has anyone ever succeeded in getting them to work together? 
 
Thanks a lot for your advice.
Sincerely,
 
Zhengzhi
