I'm trying to assign a spectrum after picking peaks. I select the peak and it will only give a resonance number to the x-coordinate. The error message reads: Exception in Tkinter callback Traceback (most recent call last): File "/sw/src/root-python23-2.3.3-23/sw/lib/python2.3/lib-tk/Tkinter.py", line 1345, in __call__ return self.func(*args) File "/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/WindowPopup.py", line 1071, in updateMenuState goto_menu.entryconfig(0, state=state) File "/sw/src/root-python23-2.3.3-23/sw/lib/python2.3/lib-tk/Tkinter.py", line 2574, in entryconfigure return self._configure(('entryconfigure', index), cnf, kw) File "/sw/src/root-python23-2.3.3-23/sw/lib/python2.3/lib-tk/Tkinter.py", line 1130, in _configure self.tk.call(_flatten((self._w, cmd)) + self._options(cnf)) TclError: unknown option "-state" The y-coordinate for the peak is not available for assignment.
