I ran through the workflow associated with the tutorial last week, and it worked fine. I can let you know that this works best at the UseGalaxy.eu server for now. This was our conversation about it Problems with RMSD analysis relate to the Guide "High Throughput Molecular Dynamics and Analysis"
Were you also able to get the workflows to run? When I looked at your history before I wasn’t able to tell what exactly went wrong, but it also looked like you were not running the workflow yet, which is why I suggest that. Do you think more is going on? How can I help with it more?
