Not those specific files directly with Prokka. The first has a permissions problem (URL is incorrect?). The second could probably be used with other tools – search the tool panel at the EU servers for available choices. One example is PfamScan. Or, search the GTN tutorials with tool names or datatypes. Each has a listing of the public Galaxy servers that host a specific tutorial’s tools. Galaxy Training!
Note: Galaxy doesn’t modify the original underlying tool. Tools are instead “wrapped” in a way that makes it easier to use them all together all in one place: to build a workflow or to share exact methods/data with others. Or if you just prefer using a GUI . The usage is (mostly) otherwise the same as the command-line.
