GetPSF with OpticStudio 20.3.1

[mtalapinto]

Hi,

I've been trying to use ln.zGetPSF() and it throws me the following error - from the experience of another issue I read about this I included a line to set the text encoding.

TXT encoding is ASCII; no change required
Traceback (most recent call last):
File "C:/Users/marce/Documents/Ckepi/pyzmx/main.py", line 30, in
getPSF()
File "C:/Users/marce/Documents/Ckepi/pyzmx/main.py", line 24, in getPSF
print(ln.zGetPSF())
File "C:\Users\marce\anaconda3\lib\site-packages\pyzdde\zdde.py", line 7820, in zGetPSF
data_spacing_line = line_list[_getFirstLineOfInterest(line_list, 'Data spacing')]
TypeError: list indices must be integers or slices, not NoneType

File "C:\Users\marce\anaconda3\lib\site-packages\pyzdde\zdde.py", line 808, in del
TypeError: 'NoneType' object is not callable

Now, if I switch the text encoding to unicode this is what I get

Successfully changed to UNICODE

I am not sure whether is a pyzdde issue, or just how the new versions of OpticStudio encode the text.
Thanks,

with kind regards,
