<div>Dear All,</div>
<div> </div>
<div>After my SPECT simulations, I obtained gate.sin file, but I got just a small point in the middle of pixel when I opened the binary file with XMEDCON.</div>
<div> </div>
<div>I would like to reconstruct this projection file, but still I could not get any satisfactory projection file to reconstruct.</div>
<div> </div>
<div>I do not know what is the problem ; my used activity or my macro???</div>
<div> </div>
<div>Do you have any idea? I also attached my macro file.</div>
<div> </div>
<div>Thank you for your help in advance.</div>

<div>The macro related with my source and projeciton part also informed below:</div>
