Hi @Akos

The genome’s assembly and build are usually in the full assembly name: what you see when using the pencil icon’s listing, or the Upload tool’s listing for “database”.

Also see [version and source of the galaxy built-in genome - #2 by Akos](https://help.galaxyproject.org/t/version-and-source-of-the-galaxy-built-in-genome/6471/2)

If there is a specific genome where you cannot find the original source, please ask. Thanks!
