I've read a paper "Sub-angstrom modeling of complexes between flexible peptides and globular proteins" which was written by Barak Raveh.et al. in 2010. They presented the Rosetta FlexPepDock protocol to model the complex between peptide and protein. They said that this protocol was implemented within revision 31671 of the Rosetta repository. But I can't find the source code of the protocol in the latest Rosetta version 3.1. Does somebody know where it is? How can I get the source code ?
