I used version 1.0.13 for the first time and it crashed with a project that has been fine with a previous version. This is the output in the shell: Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memops/format/xml/XmlIO.py: [' target = getByKey(clazz,fullKey)\n'] Deprecated: getByKey called with too short key from loadDelayedData line 1100 in /usr/local/ccpnmr1.0.13/ccpnmr1.0/python/memop ... this goes on and on and on and ends thus: ...
