<div dir="ltr"><div> </div><div>Hi Dear All</div><div> </div><div> </div>I use vGate72.vdi, Ubuntu 64-bit in Oracle VirtualBox.5.1.8_2. I know what is the problem but I don't know how to solve it. The problem is in attaching system. Every system has a defined shape and layers according to Gate Users’ Guide V.7.2. page 137. The system which I want to simulate has 16 trapezoid detectors which are 14*14 arrays (with dimensions of 6.95*6.95 mm2 at the face and 6.95*12.05 mm2 at the end) of trapezoid crystals with dimension of 0.45*0.45 mm2 and 0.45*0.814 mm2 at the front and back respectively. I used PETscanner with a single trapezoid crystal and there was no problem when I attach it to system. Since 14 trapezoid crystals have different orientation and length from center to the edge I have to define them separately in box module then I can repeat that module on the other direction. So I will have 14 sublayers. I can decrease it to 7 sublayers by repeating the submodule that they are embedded in, right below the original one inversely. But in PETscanner we can attach just 5 levels and there are no sublevels. I can’t define crystals in different levels in PETscanner because they are for the same depth. I checked it for 2 crystals and when I attached the system and ran it there was an error “COMMAND NOT FOUND </gate/systems/PETscanner/level5/attach crystal2”. Then, I tried a trick. I used OPET instead, which have 5 depths and 8 layers in the last depth. I defined the rsector, module and the crystal as a box and defined the layers as trapezoid crystals. But in OPET the last level should be wedge. So when I run the simulation I encounter that crash that I send you before. I want to know if there is any solution in which I can define a system with trapezoid crystals and at least 7 layer in the same depth. Please help me. <div class="gmail_extra"> <div class="gmail_quote">On Mon, Mar 20, 2017 at 3:30 PM, <<a href="mailto:gate-users-request@lists.opengatecollaboration.org" target="_blank">gate-users-request@lists.opengatecollaboration.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;padding-left:1ex;border-left-color:rgb(204,204,204);border-left-width:1px;border-left-style:solid">Send Gate-users mailing list submissions to <a href="mailto:gate-users@lists.opengatecollaboration.org">gate-users@lists.opengatecollaboration.org</a> To subscribe or unsubscribe via the World Wide Web, visit <a href="http://lists.opengatecollaboration.org/mailman/listinfo/gate-users" target="_blank" rel="noreferrer">http://lists.opengatecollaboration.org/mailman/listinfo/gate-users</a> or, via email, send a message with subject or body 'help' to <a href="mailto:gate-users-request@lists.opengatecollaboration.org">gate-users-request@lists.opengatecollaboration.org</a> You can reach the person managing the list at <a href="mailto:gate-users-owner@lists.opengatecollaboration.org">gate-users-owner@lists.opengatecollaboration.org</a> When replying, please edit your Subject line so it is more specific than "Re: Contents of Gate-users digest..."

I am not a PET expert, but I suspect that the actual experts will need more information about what you did before the crash happened, as well as some basic information about your software setup. We have two goals in this conversation: (1) explain to you how to run this simulation, and (2) fix our code so that when the user does something wrong she gets a useful error message instead of an embarrassing crash. So could you let us know the following: 1. software versions, release, distro: - operating system (which distro/release of linux/macosx)? - geant4, ROOT and Qt - GATE 2. the main macro for your simulation (if there is any proprietary information in your geometry, please leave it out) 3. what command line do you use to run it? if you are running in the GUI, could you also tell us the commands that you gave in there?
