I am getting a crash when I try to <br>repeat a pixel into the z direction. I am able to reproduce the <br>crash when running a slightly modified GateContrib/imaging/CT/classic/benchmarkCT.<br>I can run the original classic/benchmarkCT successfully. However, if <br>the CTScanner.mac file is modified to the one appended below, <br>Gate crashes. The output from the crash is also appended below. <br><br>I get the same results if I comment out the phantom call from benchmarkCT.mac. <br><br>I don't think that any of the geometry is overlapping. But something is <br>not right. Does anyone have any thoughts or suggestions on <br>what the problem is? <br><br>Thanks in advance for your help, <br><br>Terry<br><br><br><br>Here is the world geometry that is being used. <br><br>/gate/world/geometry/setXLength 50. cm<br>/gate/world/geometry/setYLength 50. cm<br>/gate/world/geometry/setZLength 50. cm<br><br>Here is my modified version of CTScanner.mac.
