To be honest, this was an incompatibility between the current code and
older parameter files that we hadn't anticipated.  In the context of
French & Wilson treatment, I believe the parameter basically filters
out excessively negative intensities.  I would probably leave this
alone - you can get the old parameter file to work again by resetting
it to None, which is the new default value.  The current nightly build
has been fixed to prevent it from stopping if it sees a value of 0
