Hello,
On the second point (and hopefully Rasmus will comment on the first
point), you should pick the peaks at their actual shifts, not at their
folded (aliased) positions. You can set the region for display for a
given spectrum in the Experiment --> Spectra dialog in the Referencing
tab, in the Minimum/Maximum aliased frequency columns at the right. If
set appropriately then you can pick the peaks where they belong. Then the
program will know how to properly compare peaks. If you have a peak that
is currently in the incorrect location because of folding then you can fix
that with the right mouse menu Peak --> Unalias peak dialog, by changing
the "Num. Aliasing".
