Dear allI used PET_Cylindryal program and changed the dimensions. In the full PET ring I have 12 head. I only need two head facing each other.
 /gate/head/ring/setRepeatNumber                2
For full ring I have hits, singles and Coincidences. The problem for this partial ring  is I haven't any  Coincidences in output. I have Hits and Singles but the Coincidences file is empty.Another question is, If I want to make these two heads closer to each other, Is there any way for that. 
 Please let me know if you have any idea to solve that. The program attached with this email.Best wishes Zahra
