OF exiting: list index out of range

[FritzHeiden]

Some recordings I am analysing with the OF eventually result in the same error: IndexError: list index out of range

I will share a recording with you via email.

Can you double check the recording shared on email is the right one please?

Thank you, I reran analysis on affected recordings and everything worked fine
