It appears the current toolshed implementations version 2.7.1 and 2.7.2 on usegalaxy.eu are broken? It appears they are still trying to use the default argument “skip_ani_screen”, which however is deprecated since version 2.7.0.
As a result all gtdbtk runs with the current version keep failing. But it works if you switch to version 2.6.1.
It appears this problem exists for all usegalaxy.eu users.
Who needs to be contacted and how to fix the default arguments for that toolshed-implementation?
