The Relax API runs the Rosetta FastRelax protocol.  Quoting from the RosettaCommons documentation: “This finds low-energy backbone and side-chain conformations near a starting conformations by performing many rounds of packing and minimizing, with the repulsive weight in the scoring function gradually increased from a very low value to the normal value from one round to the next.”  This  This is useful for taking a structure not generated by Rosetta and “relaxing” it into the Rosetta scorefunction preparatory to further modeling, or for generating a backbone ensemble for a further modeling experiment.

• models (directory)

  • PDB files with relaxed structures.  The models will be in the form input_####.pdb, where #### is an index (0001, increasing).  

  • Note that Rosetta will renumber the residues monotonically starting from 1, contiguous across chains.

• score.sc

  • A text file containing the Rosetta scores for each generated model.
