Clone and reproduce only differ slightly. Clone is a quick, exact data
model copy. A reproduction is a slow re-picking, at the equivalent point.
Effectively the difference is that reproduction gives different
intensities, i.e. correct for the target spectrum, and may give slightly
different peak centres due to digital resolution.
Your problem could possibly be solved by doing a reproduction, then
sorting the new peaks by intensity and eliminating those below a given
threshold.
I the long run the "Link Peak Lists" option could be modified to do what
you want more directly. Its just a bit biased towards 3D at the moment...
