If checked, the peak being assigned will be highlighted in a spectrum display
If non-zero, this will cause a number of iterations with pseudo-random start values for the coupling constants
If set, this will cause all possible combinations of coupling constant signs to be tested in iteration
In assignments, peaks can be ordered for increasing or decreasing frequency
Tolerance for grouping closeby peaks (in Hz)
If checked, closeby peaks will be grouped for assignments
For long peak lists, peaks weaker than Thresh times the highest peak will not be included in assignments
Determine how the "smearing" factor will change from one iteration to the next. Use large values to reduce the number of cycles
Determines "smearing" in the first full-lineshape iteration cycle; smaller values give stronger smearing. Use negative values for bi-exponential smearing
