IGV tutorial feedback- ENCODE file not found

Hi, I tried to explore more tutorials under Introduction to Galaxy Analyses. It is titled "Using Integrative Genomics Viewer" found here [https://training.galaxyproject.org/training-material/topics/introduction/tutorials/igv-introduction/tutorial.html](url)

I first found out that there was no background information describing the analysis, though a detailed explanation of the tool UI.

I started with the first step but I found that the ENCODE file (C2C12 RNA-Seq BAM), which I was supposed to work with was not in the list. I checked the tutorial feedbacks and I noticed that this complaint is a recurring one.

When I tried to register on GenomeSpace, [genomespace.org](url) I saw a notice that the site has been shutdown:

I also noticed that the last modification was done in 2019, can an update be done to it by the professionals?
