A similar problem occurs when temperatureor pressure series of n-dimensional spectra are to be evaluated automatically. Two slightlydifferent algorithms, AUREMOL-SHIFTOPT1 and AUREMOL-SHIFTOPT2 have devel-oped here that fulfill this task. Their performance is analyzed employing a set of simulatedand experimental two-dimensional and three-dimensional spectra obtained from three dif-ferent proteins. Peak probability and atom type based weighted averaging is introduced inorder to reduce the influence of the wrong assignment during the assignment process.
