<div dir="ltr">Dear all,
<div><br>
</div>
<div>I am trying to convert .root files to STIR projection data using the Bin_GATE utility provided by the GATE website, although the sinograms obtained don't seem to be correct in the sense that, using STIR's manip_projdata I observe that the sinograms aren't
filled in the center, despite the number of coincidences gathered (I've used files from 100 000 coincidences up to 600 000 coincidences).</div>
<div>Reconstructing the images with FBP2D I obtain some random lines which indicates a bad sinogram construction.</div>
<div>I am wondering if this is a problem with the utility Bin_GATE or if it is something I am doing wrong.</div>
<div><br>
</div>
<div>Thank you in advance,</div>
