Ab Initio

My aim – with a peptide – is to get a PDB from a FASTA without using ROBETTA server. The latest guidelines on the web about examples for AbinitioRelax refer to “rosetta_demos/abinitio/…… “. I was unable to locate “rosetta_demos” either on the general guidelines or tutorials. What I found is a PlosOne description of combined PepFlex/Dock, which, however, starts from peptide PDB, not FASTA. Thanks for indicating where the cited rosetta_demos are located.

With so many different facets, queries to Rosetta developers are most prone to be duplications. I searched through FAQs and queries. Desolate if this is another duplication.

I believe that rosetta_demos (especially any recent Rosetta demos) are only available with the Rosetta 3 releases (particularly the most recent 3.3 release). I presume from your choice of forum, you are still using a Rosetta++/Rosetta 2 release.

At this point, the Rosetta++/Rosetta 2 releases are only recommended for replicating old results, or for those few protocols which don’t yet have a Rosetta 3 version. For all new work, use of Rosetta 3 is highly recommended. Try downloading the 3.3 release, and then you should have access to the rosetta_demos directory, as well as the RosettaCON2011 Tutorials Collection (which may be a separate download).
