<div>Hi Hadi,</div>
<div><br>
</div>
<div>This warning should be related only to TOF, not to the use of PSF. It says that your input datafile implies that your scanner has an (almost) infinite precision for TOF measurements. If this is the case everything's ok, otherwise if your scanner quantizes
TOF measurements, you should provide the quantization bin or step it in the datafile header (.cdh).</div>
<div><br>
</div>
<div>All of this won't really make a difference for the reconstructed image, unless the quantization of the TOF measurements is very rough, which is probably not the case for your scanner.</div>
<div><br>
</div>
<div>Is the reconstructed image OK?<br>

<div>Dear CASToR users</div>
<div>I used TOF + psf for reconstruction a Derenzo phantom but I found this warning. </div>
<b>"Warning: quantization TOF bin size wrong or not provided, so switching to TOF list-mode reconstruction which neglects the quantization TOF bin size!"</b><br>
<div>Does it mean that I can not use psf and TOF together in CASTOR?? I need to investigate PSF+TOF. How can I do it??</div>
<div>Any help would be appreciated.</div>
