Hi Andrea,
<div><br>
</div>
<div>as long as you keep the structure of your system the same</div>
<div>and have introduced the appropriate parameters into the</div>
<div>conversion / sorting tool, the structure of the file remains the</div>
<div>same as does the file size.</div>
<div>I am not sure, but I remember that you should be able to</div>
<div>visualise the "sinograms” with a tool like “amide”. Since the</div>
<div>concersion is for producing input to STIR you may check</div>
<div>the respective users guide.</div>
<div><br>
</div>
<div>Maybe this is helpful for you.</div>
<div><br>
</div>
<div>Kind regards, </div>
<div><br>
</div>
<div>U. Pietrzyk <br>

I tried with that code but I don't understand if the output is right. Indeed, the dimension of the file in output (107.3 MB) is the same for evrey input. So, for me this is wierd and I am afraid the output is always empty. Moreover, threee warnings occur, but
I don't know if this is for them.<br>
The warning are:<br>
"Input file name is outputDerenzo*.root<br>
Michelogram file name is = Mich_sinog.s<br>
Projection file name is = Proj_sinog.s<br>
Warning in <TClass::TClass>: no dictionary for class TH1 is available<br>
Warning in <TClass::TClass>: no dictionary for class TAxis is available<br>
Warning in <TClass::TClass>: no dictionary for class TH1D is available<br>
Total Number of Coincidence Events:= 1447 "<br>

<blockquote type="cite">Hi everybody!<br>
I am working on a cylindrical PET and I have to evaluate the impact<br>
of the positron range on the quality of the images. I have some<br>
issues about retrieve an image from the coincidences of my system. I<br>
installed STIR, because I know GATE can not make an image, but how<br>
can I use my root or ASCII coincidences file on STIR?<br>
I installed also the packege GATE_PET_2_STIR but the root file is<br>
not recognized. Do you have alternatives?<br>
thank you,<br>
regards,<br>
