<p>Hi Noura, <br>
<br>
Using the DNA physics list is relatively simple. The command is:<br>
<br>
/gate/physics/addPhysicsList emDNAphysics </p>
<p>The caveat being, it ONLY works if you are using a specific
material, G4_WATER:</p>
<p>/gate/nucleus/setMaterial G4_WATER<br>
</p>
<p>If you use regular water, it won't work, it has to be G4_WATER.
You can also combine physics lists, for example if you have two
spheres and sphere 2 doesn't require the dna list, you can do
something like this: </p>
<p>/gate/sphere1/setMaterial G4_WATER<br>
/gate/sphere2/setMaterial OtherMaterial<br>
<br>
...<br>
</p>
<p>/gate/physics/addPhysicsListMixed emstandard_opt3_mixed_emdna<br>
/gate/physics/SetDNAInRegion sphere1<br>
</p>
/gate/physics/ConstructProcessMixed<br>
<br>
And then sphere1 will be simulated using the dna list, and sphere 2
with the standard list. (if you google
"/gate/physics/ConstructProcessMixed" you can find some more
examples of this).<br>
<br>
Best,<br>
