    Hello Stefan,

    Thank you so much for explaining how the index numbers work for each
    detector type! I renumbered the detector index numbers on the DCYSCORE
    cards accordingly. Initially the activity returned by RESNUCLE was
    still zero, but I then changed WHAT(1) to 3 - i.e. score all products -
    and added a second RESNUCLE detector for the volume of target nearest
    to the incident proton beam.

    Whilst the recorded activity for region 4 is still zero, I am finally
    getting some numbers from the newer detector, hurrah! I'm attaching the
    updated input file in case other folks want to see what's going on.

    Thanks again for your help. Best regards,

    Nicole.

    The indexing is separate for each type of detector, e.g. it would be
    index '1' for your RESNUCLE detector (since you have only one detector
    of that type defined) and not '3', e.g.
