Hi Patrick
in addition to what Alberto said about biasing of photonuc reactions (see
, slides 36-38 )

there are a few errors in the definitions of your scoring:
In the usrbdx, the "from" and "to" regions are both assigned to TARGET.
this will not work, you need to define a boundary, therefore the second
region should be VOID

In the RESNUCLEI, no scoring region is defined. Should be TARGET
