Sometimes you find yourself wishing to do large scale analysis of caudovirales, or a specific suptype of them. I have added a data library in galaxy, containing all 1200 odd phages known to NCBI as of 2014-07-24.
You can find this data library by clicking “Shared Data -> Data Libraries” at the top menu.
Data libraries will let you import data into your history, which you can then run the full suite of galaxy tools on. This is significantly easier than making constant requests to NCBI for datasets.
