<br>
Another Gate developer has recommend us to ask you about a the calculation of the dose uncertainty by using the DoseActor in Gate 7.1.<br>
<br>
In the pag.52 of the ppt of the Gate-RT-training that you did (<a href="http://www.creatis.insa-lyon.fr/~dsarrut/gate-training-2011/Gate-RT-training-04-2011.pdf" rel="noreferrer" target="_blank">http://www.creatis.insa-lyon.fr/~dsarrut/gate-training-2011/Gate-RT-training-04-2011.pdf</a>), it shows that we have to calculate the uncertainty in the voxels as Chetty et al. reported. Checking that paper, and since I am not sure how Gate deals the DoseActor (behind it, I mean from G4), my doubt is: should I multiply that equation by the total number of histories (N) at the end?<br>
<br>
I would appreciate if you may clarify it.<br>
Thanks in advance,<br>
Consuelo.<br>
