Reply To: Loop Modeling

I get the same errors when I run the loop modelling demo that came with the Rosetta3.0 package. Has anyone gotten this demo to run w/o getting warning messages? Is the demo incorrect? It looks the demo is reading it in as a full atom, despite only backbone being provided. However, I still get errors when I remove the full atom from the flags file.

Here are the errors from the demo.
