I copied it below again. Anybody ?</div><div class=""> I would like to use the feature for separating the phantom and detector tracking as explained in users’ guide7.1 (page 116). However, I get some errors when I try to run the example simulation example_TrackerDetector. I tried this both on a linux installation and mac installation. Phantom Tracking mode: The Root file gets generated, but I get the message below: GateToRoot::RecordEndOfAcquisition(): Failed to access to 'total_nb_primaries' histogram to fill it ! Detector Mode: I get the error below GateSource::GeneratePrimaries End of Tracks Root file reached ... Seeking for more files to open.

Note, both errors (?) are related to the primaries. 2. What are these Warnings run=1, run=2 etc ? 3. Also in the lines below doesn't Option2 overwrites Option1 ? I thought there may be a typo here. /gate/stepping/SetPolicy Option1 /gate/stepping/SetPolicy Option2 Thanks, arda </div></body></html>
