Hi Robyx,
I was able to recreate the error, and also found out the reason it reported an error:
Integrating 0 light frames, 91 light frames are ignored because their measurement failed
Maybe a better to understand error handling in the script could prevent the assumption the script was having an issue, when obviously it's my data that is the cause
When I rerun the script with exactly the same files, but choose 'Optimize Dark', then the process finishes succesfully.
I have inlcuded the log file as an attachment
Best regards,
Paul
