<p>Hello all, <br>
<br>
When I use a physics list such as emlivermore with the LET actor,
my output matrix of the LET makes sense. However, when I change
the physics list to emDNAphysics (and "setMaterial" to G4_WATER
instead of Water as required, leaving everything else identical)
my LET matrix is blank.<br>
<br>
<b>Has anyone successfully used the LET actor with the DNA physics
list, or know why this wouldn't work?</b><br>
</p>
<p>The script for my actor is the following, very basic. And like I
mentioned, it works with the emlivermore list.<br>
