[Gate-users] Using LET Actor with DNA physics list?

Hello all,

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.

*Has anyone successfully used the LET actor with the DNA physics list, 
or know why this wouldn't work?*

The script for my actor is the following, very basic. And like I 
mentioned, it works with the emlivermore list.

**

*/gate/actor/addActor    LETActor       dnaLET*

*

/gate/actor/*dnaLET*/save               output/filename.hdr

/gate/actor/*dnaLET*/attachTo           phantom

/gate/actor/*dnaLET*/setVoxelSize         0.1 0.1 0.1 um

/gate/actor/*dnaLET*/setResolution      51 51 51

/gate/actor/*dnaLET*/setType            DoseAveraged

*

Thanks everyone!

Best,
Cassandra
