Score multiple particles' fluence in a usrbin

Dear FLUKA expert,
I want to score multiple particles’ fluence in one USRBIN,for instance,Triton and Helium,but every USRBIN’s WHAT(2) can choose only one type,how should I do?

Dear @xiongbp,
Unfortunately, that cannot be done. What you can do, is to have two separate USRBINs and then add these in post-processing.
You might have a look at this thread USRBIN Subtraction plot , it might be helpful for this purpose.

Ok,I have understand it,thank you.
