Reference annotation can be extracted from the UCSC Test Table browser and sent to your active Galaxy history.
- Be logged into Galaxy in a browser window/tab
- In another window/tab, go directly to: http://genome-test.cse.ucsc.edu/
- Click into the menu Tools > Table Brower
- Set options (graphic: https://imgur.com/a/62sQd)
The "Get Data > UCSC" tool available directly within Galaxy accesses the UCSC Main Table browser which does not include this genome build.
Hope this helps! Jen, Galaxy team
