Have been trying to access the latest CS-ROSETTA tools without success for several days. Looks like http://www.csrosetta.org has been down for a while.
The person who was maintaining the csrosetta.org website has left the Rosetta community. It’s being taken over by a new person (Nik Sgourakis), but there’s a bit of a delay until he gets it up and running. Until then, you can contact him directly for CSRosetta materials: see http://niksgourakis.com/ for contact information.
