Hi Pat,<br>
<br>
you can use the "KillActor" in combination with a "particleFilter". An example from the wiki would be:<br>
/gate/actor/addActor KillActor MyActor<br>
/gate/actor/MyActor/save MyOutputFile.txt<br>
/gate/actor/MyActor/attachTo MyVolume<br>
/gate/actor/MyActor/addFilter particleFilter<br>
/gate/actor/MyActor/<wbr>particleFilter/addParticle e-<br>
/gate/actor/MyActor/<wbr>particleFilter/addParticle e+<br>
<br>
>From my experience, this stops the track whenever a given particle type (here e- or e+) enters the volume labeled "MyVolume" and generates a hit at the entrance positon.<br>
This will be used correctly in the digitizer afterwards.<br>
I used this setup for my PET application and successfully filtered gamma events.<br>
But be aware, that at least for Gate v7.2 this results in significant increase of memory consumption while simulating. This gets worse the longer you simulate.<br>
I tried to solve the issue by playing with settings like " setResetDataAtEachRunFlag" and other options but did not manage to succeed.<br>
Maybe another GATE user can jump in and help at this point.<br>
<br>
Best,<br>
Moritz<br>

Dear Gater,<br>
Is it possible to forced gamma rays or electrons to absorb in specific volume (detector)?<br>
And so, I know that Kill actor could kill tracks entering the volume, but is it possible to kill tracks entering the volume, in digitizer mode (imaging system?<br>
<br>
Regards,<br>
Pat<br>

Dear Gate users,<br>
<br>
I would like to extract the info of the .root file generated during the<br>
simulation. The problem that I have is that this .root file store the<br>
energy deposited in many histograms (one for each position of the source),<br>
for example I have:<br>
edep Histo,1<br>
edep Histo,2<br>
edep Histo,3<br>
edep Histo,4<br>
edep Histo,5<br>
edep Histo,6<br>
<br>
I can not find the way to access the tree and extract the info for an<br>
specific Histo.<br>
<br>
If some one has some experience I appreciate any help.<br>
<br>
Best regards.<br>
Maikol<br>

This description (RAM usage increases during Gate run to problematic levels) actually sounds to me very much like a bug, like a typical memory leak.<br>
<br>
Whenever Gate does things like this, please consider reporting this as an "issue" on GitHub (<a href="https://github.com/OpenGATE/Gate/issues" rel="noreferrer" target="_blank">https://github.com/OpenGATE/<wbr>Gate/issues</a>).<br>
(And if you would like to be really helpful: verify that the problems you observe are reproducible with the latest release, or even better, with the develop version from GitHub!)<br>
<br>
Thanks,<br>
David<br>
