Error Loading project from V2 to V3

Dear CCPN Team,

I am trying to open a saved project. I believe the said project was created on V 2.5.2 and I am trying to open on version 3.1.1 (System MacOS 12.6.3).

While trying to load the project, the terminal traceback starts like this:

INFO : Validating Project integrity… (Project._getAPIObjectsStatus:1451)
2023-04-04 18:51:49.031 CcpNmrAnalysis[3067:100380] -[NSApplication runModalSession:] may not be invoked inside of transaction begin/commit pair, or inside of transaction commit (usually this means it was invoked inside of a view’s -drawRect: method.) The modal dialog has been suppressed to avoid deadlock. (

1 libqcocoa.dylib 0x0000000116ff790a qt_plugin_instance + 141749

The terminal keeps running for several minutes until it crashes. The error is: Error loading “/myfolder_name/my_project_name.ccpn”: Cannot save: undefined apiTopObject

Could you please guide on how to solve this issue?

Thank you very much in advance,

Hi Karen,

the best thing is if you send us your project to and we’ll take a look. No need to include the spectra.



Thank you, I will send it.

Best regards,
