Long shot, but does anyone know the study, experiment, or paper where the full test data comes from? It is a knockout using a cre system but I don't know what exactly was knocked out.

Looks like it was added by @Oskar Wacker https://github.com/nf-core/test-datasets/pull/682 (not sure if he is still checking slack though)

I asked @Susanne Jodoin this morning, she might know

I am still on this issue and it is unfortunately not clear yet if there is a publication to it. In case there is no publication we should decide on a replacement.

Don't worry if you can't find, it doesn't have to be published data, that wasn't the issue, Evan was just curious on its origins for some things he was trying out.
