My guess is that your file name was read from a json files or something and as a result is Unicode not just string type. Are your variables file variables? If so you might want to make them transient variables (v = v() ) Also when you open your file try: F=cdms2.open(str(filename)) it might fix the Unicode issue. Sorry 2.4.1 is so old, it’s hard to support these sort of things. I will try to reproduce your issue with 2.8 C.

Hi,
cdms2.open(str(filename)) is not helping. i am getting the same error.

I have attached the code (in .zip)
four_panel.py.zip

Thanks
