After installation of the most recent upgrade, I get the following on starting analysis: Traceback (most recent call last): File "/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/AnalysisGui.py", line 62, in ? from ccpnmr.analysis.AnalysisPopup import AnalysisPopup File "/ccpnmr/ccpnmr1.0/python/ccpnmr/analysis/AnalysisPopup.py", line 102, in ? from ccpnmr.analysis.CalcShiftDifferencePopup import CalcShiftDifferencePopup ImportError: No module named CalcShiftDifferencePopup Reversion to the old version of AnalysisPopup.py eliminates this error. The added line in the new version of AnalysisPopup.py that reads from ccpnmr.analysis.CalcShiftDifferencePopup import CalcShiftDifferencePopup is requesting a popup module that is not in the existing code and does not appear on the upgrade server.
