Automating RSA Calculations

Hello!

I am attemting to automate seismic analysis through Dynamo. The seismic loadings are created in Robot Structural Analysis, so I am attemping to import the loads from the Robot file into my Dynamo graph. However, the calculation does not run and the Analysis.Calculate node says there are no Loads and Load Cases within the list.

As the node will run calculations through the Robot file where the loads are already determined, why does it not accept these values?
