[Gate-users] Fwd: A bug report on version 7.2 using Tracker Detector mode

[韩匆]

Dear Madam/Sir,

Hello. I encounted a problem when I tried to execute the example macro of
Tracker Detector mode in GATE v7.2. The error information is explained
below.

To put it in a simple way, I think the GATE v7.2 can not terminate the
simulation in the Detector mode and always tries to seek more files to
open. So is there any easy approach to solve this problem for v7.2? Many
thanks!

GATE Version 7.2
GATE macro: example_TrackerDetector
When executing the Tracker model, it pops the error when the program
finishes:
*"WARNING - Attempt to delete the physical volume store while geometry
closed !*
*WARNING - Attempt to delete the logical volume store while geometry closed
!*
*WARNING - Attempt to delete the solid store while geometry closed !*
*WARNING - Attempt to delete the region store while geometry closed !*
*GateToRoot::RecordEndOfAcquisition(): Failed to access to
'total_nb_primaries' histogram to fill it !"*

When excuting the Detector model, the program goes to *the endless loop*.
After interpreting the program, the error is :
"*GateSource::GeneratePrimaries   End of Tracks Root file reached ...
Seeking for more files to open.*
* GateSource::GeneratePrimaries   End of Tracks Root file reached ...
Seeking for more files to open.*

*Session terminated.*

*-------- EEEE ------- G4Exception-START -------- EEEE -------*
**** G4Exception : UI0001"*

The file created by Tracker mode is 234 Mb and for Detector mode is 322 Kb.
But there is some useful simulated data in both files. So I think the
simulation works for v7.2, but can not be terminated properly.


If we execute the same script of Tracker mode on GATE Version 7.1, there is
no error popped out like v7.2. And The Detector mode can be executed and
terminated in the right way with a output of 322 Kb as well. However, there
is till some error message.
*"GateSource::GeneratePrimaries   End of Tracks Root file reached ...
Seeking for more files to open.*
*[Acquisition-0] Slice 1 from 1 to 1 s [slice=0 s], final stop at 1 s.*
* <!> *** WARNING *** <!>  Warning in GateApplicationMgr::GetTimeSlice,

* GateSource::GeneratePrimaries   End of Tracks Root file reached ...
Seeking for more files to open.*
*[Acquisition-0] Slice 2 from 1 to 0 s [slice=0 s], final stop at 1 s.*
* <!> *** WARNING *** <!>  Warning in GateApplicationMgr::GetTimeSlice,

*GateApplicationMgr.cc (l.218): Error in GateApplicationMgr::GetTimeSlice,
run=2*

*WARNING - Attempt to delete the physical volume store while geometry
closed !*
*WARNING - Attempt to delete the logical volume store while geometry closed
!*
*WARNING - Attempt to delete the solid store while geometry closed !*
*WARNING - Attempt to delete the region store while geometry closed !"*

Thus we can see v7.1 and v7.2 have the similar simulation results. But both
have some errors in the problem, which might need to be fixed.
