Dear all,
I noticed that in the input file I sent in card ROTPRBIN WHAT(6) is
wrongly set to 0.0 instead of 1.0. However it does not affect my
question, because of running it with the correct WHAT(6)=1.0 returns to
give the same wrong results in scored doses.
Sorry and thanks again for your support.
Cheers
Oscar
