<p>Dear Yu,</p>
<p><br>
</p>
<p>The random sinogram is mandatory to convert data into Castor
format. When using e7tools, you can have access to the smoothed
random sinogram (like the scatter sinogram..). It is named
something like smoothed_rand_xx.s. This is directly the estimated
random sinogram (with low variance) as computed by the approach
developed by V. Panin.</p>
<p>Best,</p>

<div dir="ltr">Hi All,
<div><br>
</div>
<div>I am trying to use the tool for the conversion of
Siemens Biography mCT PET data to the CASToR data file
format. In this tool, there are four mandatory options
(output name, normalization sinogram, prompts sinogram and
random sinogram). However, after using e7 toolbox, I do
not have a random sinogram. How to solve this problem? </div>
<div><br>
</div>
<div>By the way, anyone using CASToR is from Australia or
China? </div>
<div><br>
</div>
<div>Best wishes!</div>
