Hi, From the Edit Spin Systems popup, I tried to display strips of a spin system(via the button at the top) in a 3d window. The x and y are proton with the nitrogen dimension orthogonal. I get the following error message. Exception in Tkinter callback Traceback (most recent call last): File "/home/justin/Programs/ccpn/ccpnmr/python2.4/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__ return self.func(*args) File "/home/justin/Programs/ccpn/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/EditSpinSystemPopup.py", line 182, in displayStrips displaySpinSystemStrips(self.guiParent, spinSystems, window) File "/home/justin/Programs/ccpn/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/WindowBasic.py", line 1398, in displaySpinSystemStrips shifts, yShifts = getSpinSystemWindowShifts(spinSystems, window, shiftList=None) File "/home/justin/Programs/ccpn/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/WindowBasic.py", line 1312, in getSpinSystemWindowShifts if ranges[i][0] > minVal: IndexError: list index out of range
