Hey everyone, I appear to have a problem displaying a pseudo-3D spectrum. I loaded in without problem and was used for transferring assignments to, but now it is displaying as shown in the attached pdf. The following traceback was displayed: Warning: spectrum (TROSY_HSQC_1_FF, hsqc_2): data file /afs/gorlaeus.net/users/s/skinnersp/P450_frankfurt/P450cam800/7_spectra/7/hsqc_2.ft2 not accessible >>> Exception in Tkinter callback Traceback (most recent call last): File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/python2.6/lib/python2.6/lib-tk/Tkinter.py", line 1410, in __call__ return self.func(*args) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/memops/gui/ScrolledWindow.py", line 1032, in <lambda> cmd = lambda event, button=button, state=state: self.releaseFunc(event, button, state) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/memops/gui/ScrolledWindow.py", line 1005, in releaseFunc func(event) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/memops/gui/ScrolledWindow.py", line 1597, in selectLocation self.select_single_func(event.widget, a, b, x, y, button, state, event=event) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/ccpnmr/analysis/frames/WindowFrame.py", line 1936, in selectSingle self.menuPeak = self.createNewPeak(a, b, row, col) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/ccpnmr/analysis/frames/WindowFrame.py", line 2001, in createNewPeak parent=self.topPopup, doFit=False) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/ccpnmr/analysis/core/PeakBasic.py", line 1705, in addPeak setPeakPosition(peak, position, tile) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/ccpnmr/analysis/core/PeakBasic.py", line 1815, in setPeakPosition peakDim.position = position[dim] File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/ccp/api/nmr/Nmr.py", line 55061, in setPosition + ": %s" % (value,) ApiError: ccp.nmr.Nmr.PeakDim.setPosition: position constraint position_ge_1 violated by value: 0.0 Exception in Tkinter callback Traceback (most recent call last): File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/python2.6/lib/python2.6/lib-tk/Tkinter.py", line 1410, in __call__ return self.func(*args) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/python2.6/lib/python2.6/lib-tk/Tkinter.py", line 495, in callit func(*args) File "/afs/gorlaeus.net/lic/metprot/software/ccpnmr/ccpnmr2.1/python/ccpnmr/analysis/frames/PeakTableFrame.py", line 999, in updatePeaksFromList value = sampledDim.pointValues[int(peakDim.position)-1] TypeError: int() argument must be a string or a number, not 'NoneType' I guess the first part refers to a spectrum that has been moved, but I don't know about the rest. Any ideas? Thanks, Simon
