data.importConditions throws an error because, it seems, the strings are being converted to Qstring. This is with both PsychoPy 1.85.3 and 1.85.6 in Windows 10.
No issues on a Mac (have only tried 1.85.6).
I did have another Qstring issue on a Mac: It looks like strings are being saved as Qstrings and then can’t be unpickled because the unpickling function in PsychoPy assumes a string.
(stimList,fieldNames) = data.importConditions(fileName,returnFieldNames=True)
File “C:\Users\LupyanLab\Miniconda2\lib\site-packages\psychopy-1.85.6-py2.7.egg\psychopy\data.py”, line 2674, in importConditions
