Dead pixel detection procedure?

I am on version 4.1.0 Cortex for Dailies. I see that a .csv dead pixel report is generated every time I output deliverable files from Cortex. This is good news. However, when I open them, they are empty except for the header columns.

I can’t find any documentation in the user guides (v1.5 is the most recent I can find) about how to run this feature.

Is there a resource anyone can point me at for learning to use this feature in 4.1.0 for Dailies?

There is a Tutorials button in the top right corner of Cortex. Even though the tutorials say v3, the procedure is mostly the same. You will want to pay particular attention to the QA tool tutorials.
