ProcessHits() "not visible" while reading root geometry file [message #5186]

Hello,

when I want to read a root file with emc geometry,
program does not go into the ProcessHits() function
(PndEmc.cxx) which uses TVirualMC.cxx
and that's why I can not get Points for this detector
(the geometry of this detector is plotted correctly).

Does anybody know why?

Thanks in advance!

Ola.

Hi,

If I understand you well, you want to use root files for the geometry (like in the MVD) So I think you follow the procdure used in MVD and implemented the construct geometry methods! did you also implement a method analoge to CheckIfSensitive()? to decide (e.g. using names) which volume is sensitive! in fact the ProcessHits() function will be only called if Geant stepping enter a volume which is marked sensitive.

regards

Mohammad

Hi Mohammad,

yes, exactly, I want to use root files for the geometry (like in the MVD or dch) and I followed the way of dch detector, where I added to sensitives crystals by their names.
I also tried to use the CheckIfSensitive() methods (like it is done for mvd), but somewhere I still miss something, because I have exactly the same effect that detector is plotted (so I guess that in some part crystals are added to sensitives), but still I can't see ProcessHits() function running.

Regards,
Ola.

Hallo,

Ok, can you make a tar file of your emc directory and send it to me with the root geometry file.

Hi Mohammad, Dima,

it seams that my problem is solved (thanks to Johan)
and it works now Very Happy

The problem was with: where and how the volume with forward endcap
was added to the mother volume (Cave).

Thanks a lot!

Best wishes,
Ola.
