Analyze the activation index?

I’m an obsessive compulsive when it comes to completing Halo’s, so it was natural that I had to have 45/45 objects scanned with the Kinect library. My problem is I’m at 44. After looking online, what I’m missing is the activation index. I’ve played through the library 3 times now trying to analyze it, but no matter what I can’t. I can’t analyze it from a distance, and getting close activates the cutscene. Anyone else gotten it or having trouble getting it?

Wow I’m an idiot. You do it at the very beginning, not the end. When you enter the very first area with the open pit, the index is floating in the middle. Sorry for the pointless thread.
