Visualize microyz module

Hello!
I work on microyz. I want to check that the steps of visualization are true, please.
1- write

sarahabdelaziz@Sarahs-MacBook-Pro microyz-build % ./microyz microyz.in
....
========================================================================================
--> G4TaskRunManager::CreateAndStartWorkers() --> Creating 5 tasks with 1 events/task...

2- then open plot.C by

sarahabdelaziz@Sarahs-MacBook-Pro microyz-build % root plot.C
...
root [0] 
Processing plot.C...
**** Results ****

---> yF =7.65877 keV/um
---> yD =8.59941 keV/um

---> Limits: 
     * min value of y = 4.86869 keV/um
     * max value of y = 12.0757 keV/um
root [1] 2025-01-01 14:44:38.466 root.exe[18663:3624054] +[IMKClient subclass]: chose IMKClient_Modern
2025-01-01 14:44:38.466 root.exe[18663:3624054] +[IMKInputSession subclass]: chose IMKInputSession_Modern

And I got the histogram.
3- to visualize

sarahabdelaziz@Sarahs-MacBook-Pro microyz-build % ./microyz

I want to visualize the data from the microyz.in, In here The TrackerSD radius is set to 0 fm , but the default value in the code is 2 nm. So, how can I let it to visualize mcaro file (microyz.in)?
When the Idel prompt is opened I write

/control/execute/ vis.mac

When I write

/control/execute microyz.in

I got

***** Batch is interrupted!! *****

I attached the photo, which has a red line, what dose this mean, please?
Happy New Year!

Hi Sarah

Happy New Year to you too.

I’m afraid I’m going to be tough here. It’s not really our job to debug users’ code. Moreover, only you can know whether the results are “right” or not. Do they match your expectations? Visually, are the tracks doing what you expect? Of course, we can help - and there are many willing Geant4 helpers - but I think you need to go back to the documentation and try some simple examples until you understand what is going on. And just try a few things.

For example, as suggested by one respondent, try a larger world volume.

Good luck
John
