Now I used the line list_image_info for retrieving information about my image, but, as I supposed, image min, image max and image sum are zero. Now I have to understand if the problem is in GATE or in STIR. Can you check if my steps in STIR are all right? So, after I had the root file from GATE, I used the code Bill_Gate_v1.0.C to take the sinogram. Then, I reconstructed the image in format .v with FBP2D, using the line ">FBP2D FBP2D.par" changing the file name inside the .par file. Maybe are the coincidences too few? they are 1447.<span class=""><br> <br> Il 2016-06-15 17:43 Pietrzyk, Uwe ha scritto:<br> </span><blockquote type="cite">Hi Andrea,<div><div class="h5"><br> as long as you keep the structure of your system the same<br> and have introduced the appropriate parameters into the<br> conversion / sorting tool, the structure of the file remains the<br> same as does the file size.<br> I am not sure, but I remember that you should be able to<br> visualise the "sinograms” with a tool like “amide”.
