Hey everybody, I have a problem concerning my peak list from a NOESY spectra. I have assigned almost all peaks and tried to create the distance constraints (Structure -> Make Dist. Constraints), selected my NOESY spectra and the correct peak list. Constraint Set was number 1. But ccpn didn't calculated any distance constraints. Now I tried to take a look on the peak list (Crosspeaks -> Edit Peak List). I've selected the NOESY spectra, but I'm not able to choose my peak list. There's only 'none'. This may be the problem why it is not possible to create my constraints set? On the console is the following message when I'm selecting the NOESY peak list. Exception in Tkinter callback Traceback (most recent call last): File "/usr/lib64/python2.4/lib-tk/Tkinter.py", line 1345, in __call__ return self.func(*args) File "/opt/ccpnmr/temporaryReleaseDir/ccpnmr/ccpnmr1.0/python/memops/gui/PulldownMenu.py", line 288, in <lambda> File "/opt/ccpnmr/temporaryReleaseDir/ccpnmr/ccpnmr1.0/python/memops/gui/PulldownMenu.py", line 444, in setSelectedIndex File "/opt/ccpnmr/temporaryReleaseDir/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/EditPeakListPopup.py", line 561, in changeSpec self.changeList(i, selectedList) UnboundLocalError: local variable 'selectedList' referenced before assignment Hopefully my whole work isn't lost. with best regards Marco -- Dipl.
