Also the SPECT-version</div><div>may even be helpful. There you can see how to differentiate </div><div>between different types of event and how they are counted</div><div>to finally calculate the number of detected events or</div><div>coincidences given a number of primary events.</div><div>Furthermore you can apply additional cuts to eliminate</div><div>scattered events, etc.</div><div><br></div><div>Probably some easier examples of using the root file and</div><div>how to apply a simple means to evaluate the simulation</div><div>you may also find within the EduGATE examples available</div><div>for free on the OpenGATE webpage. There are also</div><div>README-files available.</div><div><br></div><div>I hope this helps for the moment!</div><div><br></div><div>All the best and kind regards,</div><div><br></div><div>Uwe Pietrzyk</div><div><br></div><div><br><div> <div style="color: rgb(0, 0, 0); letter-spacing: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: auto; word-spacing: 0px; -webkit-text-stroke-width: 0px; word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;"><div><span style="orphans: 2; widows: 2;">/----------------------------------------------------------------------</span></div><div style="orphans: 2; widows: 2;">Prof. Dr. Uwe Pietrzyk<br>Diplom-Physiker<br>Institut für Neurowissenschaften und Medizin / INM-4<br>Forschungszentrum Jülich GmbH<br>52425 Jülich<br>Tel: +49-2461-61 4763<br>Fax: +49-2461-61 2820<br>Mobil: +49-162-103-4871<br>eMail: <a href="mailto:U.Pietrzyk@fz-juelich.de">U.Pietrzyk@fz-juelich.de</a><br><a href="http://www.fz-juelich.de/inm/inm-4/DE/Home/home_node.html">http://www.fz-juelich.de/inm/inm-4/DE/Home/home_node.html</a><br>&<br>Bergische Universität Wuppertal<br>Fakultät für Mathematik und Naturwissenschaften</div><div style="orphans: 2; widows: 2;">Büro: D.08.01<br>Gaußstr. 20<br>42097 Wuppertal<br>Tel: +49-(0)202-439-3523<br>Fax: +49-(0)202-439-2811<br>eMail: <a href="mailto:Uwe.Pietrzyk@physik.uni-wuppertal.de">Uwe.Pietrzyk@uni-wuppertal.de</a><br><a href="http://www.medizinphysik.uni-wuppertal.de/">http://www.medizinphysik.uni-wuppertal.de</a><br>----------------------------------------------------------------------/</div></div> </div> <br><div><div>On 23 Dec 2016, at 23:13, Milad Fard <<a href="mailto:miladfard.mailbox@gmail.com">miladfard.mailbox@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><div dir="ltr"><div><div>Thanks for your fast reply, this is helps me already a lot.
