Hello,  
My HISAT2 files finished uploading and I wanted to view the data by clicking the eyeball icon, but I received this message: “Unknown or invalid visualization: igv”  
Can anyone help with this?  
Thank you!

Hi @jmachuca10

Let’s combined your question into the other one where the developer’s responded.

> [@Cannot Preview BAM File on usegalaxy.org – "Unknown or invalid visualization: igv"](https://help.galaxyproject.org/t/cannot-preview-bam-file-on-usegalaxy-org-unknown-or-invalid-visualization-igv/15561/4):

> Sorry for the inconvenience here – during the release candidate for 25.0 we got a little ahead of our skis. What you’re seeing is Galaxy trying to use the visualization-first framework for previewing datasets ([Visualization-First Display functionality by dannon · Pull Request #20190 · galaxyproject/galaxy · GitHub](https://github.com/galaxyproject/galaxy/pull/20190)). Deployed on main, bam is currently configured to use igv.js, which isn’t _quite_ yet available.

Thanks! 🙂
