<div dir="ltr"><div><div><div>So the general setup of a Gate simulation (which is unfortunately not that clear on the website or wiki) is that you define geometry, source(s) and then actors (which is simply what scorers are called in Gate), which save output. I was not even aware that you could do what you do.<br><br></div>Of course, it is often that you want to score specific particles. You can use existing actors and apply filters to store only the particles you need. The filter might restrict the particles to a certain species (e.g. only photons) or on production processes. I do not know if there's a filter that restricts the particles to only those that underwent Compton scattering (check the wiki to see what's available, or look in the example directories, maybe someone does the same). If you find nothing that helps you, you can write your own filter, or modify/copy an existing actor. <br><br></div>Hope that helps,<br></div>Brent<br></div><div class="gmail_extra"><br><div class="gmail_quote">2016-06-02 15:42 GMT+02:00 Pawe Kowalski <span dir="ltr"><<a href="mailto:pawkowalski@yahoo.com" target="_blank">pawkowalski@yahoo.com</a>></span>:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue,Helvetica Neue,Helvetica,Arial,Lucida Grande,sans-serif;font-size:16px"><div><span>Hi Brent,</span></div> <div><br></div><div>Thank you again for your answers.</div><div><br></div><div>I generate my output just using commands:</div><div><div>/gate/output/root/enable</div><div>/gate/output/root/setFileName output/output</div><div dir="ltr">/gate/output/root/setRootHitFlag 1</div></div><div>After simulation I analyze root files using c++ code.</div><div><br></div><div><div>If I don't specify any actor, is there a default one?

Assuming it's the PhaseSpaceActor, there is an option called EnableCompact that reduces the number of saved fields. It reduces to the ones I care about, so it may not be what you need. I suppose per-field switches could be better. Storage space taken up is quite little though, so the easiest solution is to simply ignore the fields you don't use. Alternatively, you can adapt the actor to suit your needs. Perhaps using filters will help you with some of the things you need, but for coincidence selection you either record time and do some post-processing or dig down into the actor that you use to record.<br clear="none"><br clear="none"></div>Cheers,<br clear="none"></div>Brent<br clear="none"><div><div><br clear="none"><br clear="none"><div><div><div> ----------------------------------------------------------------------<br clear="none"> <br clear="none"> Date: Fri, 27 May 2016 12:04:51 +0000 (UTC)<br clear="none"> From: Pawe Kowalski <<a rel="nofollow" shape="rect" href="mailto:pawkowalski@yahoo.com" target="_blank">pawkowalski@yahoo.com</a>><br clear="none"> To: GATE-mailingList <<a rel="nofollow" shape="rect" href="mailto:gate-users@lists.opengatecollaboration.org" target="_blank">gate-users@lists.opengatecollaboration.org</a>>,<br clear="none"> "<a rel="nofollow" shape="rect" href="mailto:gate-devel@lists.opengatecollaboration.org" target="_blank">gate-devel@lists.opengatecollaboration.org</a>"<br clear="none"> <<a rel="nofollow" shape="rect" href="mailto:gate-devel@lists.opengatecollaboration.org" target="_blank">gate-devel@lists.opengatecollaboration.org</a>><br clear="none"> Subject: [Gate-users] Modification of GATE output<br clear="none"> Message-ID:<br clear="none"> <<a rel="nofollow" shape="rect" href="mailto:828474961.263737.1464350691463.JavaMail.yahoo@mail.yahoo.com" target="_blank">828474961.263737.1464350691463.JavaMail.yahoo@mail.yahoo.com</a>><br clear="none"> Content-Type: text/plain; charset="utf-8"<br clear="none"> <br clear="none"> Hi,<br clear="none"> I have few questions about modifying Root output from GATE simulations.<br clear="none"> 1.
