CYANA Variable: tolerance

Initial value: 0.02,0.02,0.4,0.4

Tolerance ranges Dtol between peak positions and proton chemical shifts (in ppm). In automatic NOESY assignment, these values are used for atoms that are already used in peak assignments of the current peak list. The value of tolerance is a comma-separated list of values for the different spectral dimensions: the first and second numbers apply to protons, the third number to 13C or 15N. The second number is for protons that are directly bound to the corresponding 13C or 15N atom, the first number for other protons.
