Dear Taku, my two cents.... I just tried the examples/example_PET/PET_CylindricalPET_System.mac and I did not encounter any issues with the Coincidence sorter. I got the coincidences tree in my root output file. I also got all the ascii output files using the GATE commands: /gate/output/ascii/enable /gate/output/ascii/setFileName myascii Regards, vesna <div class="gmail_quote">On Fri, Nov 16, 2012 at 10:38 AM, 山中琢 <<a href="mailto:takuyama@med.hokudai.ac.jp" target="_blank">takuyama@med.hokudai.ac.jp</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I recently upgraded to v6.2 and found there is no /gate/digitizer/Coincidence... or /gate/output/ascii... The latter was mentioned by someone but seemed not having an answer. These functions are very essential in my research(well, coincidences are important for everyone). I also want to know whether there is a description about the modification between each versions. I don't want to find those modifications by myself with the big "ERROR" or "COMMAND NOT FOUND" and go back to the whole code each time. Furthermore, maybe because it is overwritten from the older versions, the user's guide v6.2 has the same functions as the older ones and this makes us confused. <a href="http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.2" target="_blank">http://wiki.opengatecollaboration.org/index.php/Users_Guide_V6.2</a> I'm very glad to have this wonderful application and want to thank you the members trying to upgrade. But if things keep going like this, I don't think no ones going to use the upgraded version... -- Hokkaido University, Graduate school of medicine, medical physics and engineering D1 Taku Yamanaka <a href="mailto:takuyama@med.hokudai.ac.jp" target="_blank">takuyama@med.hokudai.ac.jp</a> -- _______________________________________________ Gate-users mailing list <a href="mailto:Gate-users@lists.opengatecollaboration.org">Gate-users@lists.opengatecollaboration.org</a> <a href="http://lists.opengatecollaboration.org/mailman/listinfo/gate-users" target="_blank">http://lists.opengatecollaboration.org/mailman/listinfo/gate-users</a> </blockquote></div>
