On the SlicerIGT tutorial page, the link for lesson U-03 in the “Common Topics” section is broken and I cannot open it. I wanted to connect the NDI Aurora Sensor to 3D Slicer using the Plus Toolkit and import the positional information measured by Aurora in 3D Slicer, but I do not know how to connect it and am having trouble. Could anyone please fix this as soon as possible?

I was just able to access this via the link at [User tutorials | SlicerIGT](https://www.slicerigt.org/wp/user-tutorials/). Does that work for you?

Hi mikebind!

I have already tried that link, and it did work. I appreciate you for your advice.

So this post is turning into a warning that the “U-03” link on the tutorial page is broken.
