Rosetta 3.7

New and updated applications

New features and classes

  • A new introductory tutorial system has been added under the demos/tutorial/ directory. These can also be found online at https://www.rosettacommons.org/demos/latest/
    • The introductory tutorials cover both basic concepts (packing, minimization, fullatom/centroid) as well as demonstrations on how to use some of the most commonly used Rosetta protocols (ab inito, comparative modeling, loop modeling, design, protein-protein docking and protein-ligand docking).
    • Additional demos are now listed thematically, to assist in locating relevant demos.
  • Many new ResidueSelectors
  • PDB reading can handle LINK records in most cases
  • "Spell checking" for options: suggestions for the desired option if the user's options are invalid
  • AACompositionEnergy takes fractional compositions in addition to counted-out compositions
  • New score term to penalize peptide sequences that form aspartimide
  • New script for setting up the pyrosetta environment

Bugfixes

  • loops::restrict_kic_sampling_to_torsion_string repaired (for KIC loop modeling)
  • BridgeChainsMover repaired to match publication

Rosetta 3.6

After releasing Rosetta 3.5 in 2013, Rosetta transitioned to a weekly release system. Rosetta 3.6 is weekly release v2016.13-dev58602. We are marking it as 3.6 to meet the needs of users that require numbered releases instead of weeklies. This large set of release notes collects changes released in weekly releases since their inception.

New scorefunctions:

Since Rosetta 3.5, the default scorefunction was updated two generations, to Talaris2013 and then to Talaris2014 .
We’ve also updated the default minimizer to LBGFS, which is expected to provide better performance on the average problem.

New applications:

New tools:

  • Batch-distances
  • Residue_energy_breakdown
  • Reference poses: store a pose “snapshot” at a particular point in a protocol, and use the residue numbering in that pose to control behavior of modules at a downstream point, even if the residue numbering has changed (due to loop insertion, etc.).
  • Energy function weight optimization (not suggested for end-user use, but if you’re brave…)
  • A large number of RosettaScripts Movers, Filters, TaskOperations, etc. added. These include:
    • Disulfidize: Add disulfide bonds to a pose, trying all permutations to find best disulfide placement.
    • Perturb by torsion bins (InitializeByBins, PerturbByBins movers): Perturb a conformation based on statistical probability of finding residue i in torsion bin B, and residue i+1 in bin B’.
    • GeneralizedKIC mover: general kinematics-based loop closure for arbitrary chains of atoms that can include stretches of canonical or noncanonical backbone, side-chains, ligands, etc.
    • Parametric design tools (MakeBundle, PerturbBundle, and BundleGridSampler movers; BundleReporter filter): fragment-free sampling of coiled-coil tertiary structures. Fully generalized for strands or helices made of canonical or noncanonical building-blocks.
    • LayerDesign and LayerSelector: design with different sets of residue types depending on burial and/or secondary structure. LayerDesignOperation, LayerSelector
  • FeaturesReporter framework for structural analysis using Rosetta (was in 3.5, but is a more complete system now)

Miscellaneous new features:

  • Rosetta’s Boost version updated from 1.46 - > 1.55
  • Internal smart pointer model altered to match C++11, along with other changes looking forward to C++11
  • Major updates to MR-Rosetta
  • Loop Modeling:
    • Extension of KIC loop modeling to non-canonical backbones (beta amino acids, etc) with GeneralizedKIC (see above).
    • Continued development of next-gen KIC, including compatibility with fragments-based modeling
  • Multiple refactorings in the chemistry layers, allowing:
    • Poses with carbohydrates
    • Better support for ribonucleoprotein
    • Support for all ligands in the PDB’s chemical dictionary (note you must install that dictionary separately)
    • Support for runtime manipulation of chemistry (adding/removing atoms)
    • Support for rotamer libraries with arbitrary numbers of backbone torsion dependencies
    • Automatic setup of bonds to metal ions.
  • Much better support for D-amino acids. Mirror-image conformations now score identically with the talaris2013 and talaris2014 scoring functions. D-residues use rotamer and scoring databases for their L-counterparts.
  • Support for mirror-image symmetry operations in symmetric poses, with proper conversion between D- and L-amino acid residue types.
  • Support for non-pairwise-decomposable score terms during packing
  • New non-pairwise-decomposable score term to guide design that penalizes deviations from a desired residue type composition.
    • New “sequence constraints” to control the residue type composition of a sub-region of a structure (e.g. a protein interface) during design.
  • New neighbor radii for canonical amino acids
  • ResidueSelector hierarchy as a selection syntax
  • FloppyTail now compatible with symmetry
  • Much better support for noncanonical residue linkages, such as N-to-C cylization, sidechain-backbone linkages, etc.
  • Full Database support and documentation (SQLITE3, MySQL, etc)

Performance, usability improvements, bug fixes:

  • 10% speed improvement in etable evaluation (faster scoring). Reduced memory use.
  • Automatic backtrace reporting upon crash, for better debugging
  • Beautification: yes, we finally have a codebase-wide single style format, enforced by an external beautification script
  • Repair of the longstanding “ResidueType explosion” malfeature, reducing memory use dramatically and improving Rosetta boot-up time
  • SASA machinery completely overhauled. Default SASA radii changed to the Reduce set, which include hydrogens by default. It was previously using a radii set that was never published. SASA Calc settings can be changed through options system.
  • New documentation wiki

Rosetta 3.4

Released Sunday, March 25, 2012

  • Point mutant scan application: The purpose of this protocol is to increase the stability of a protein of interest with only single or double point mutants.
  • Non canonical amino acid utilities: This feature includes 2 applications:
    1. MakeRotLib - This application creates a noncanonical amino acid rotamer library
    2. UnfoldedStateEnergyCalculator - This application calculates the explicit unfolded state energies.
  • RNA assembly with experimental pair-wise constraints: This code is intended to take an RNA sequence and secondary structure and then give three-dimensional de novo models of the helices and inter-helical motifs, and then build up the complete model from these parts.
  • RNA 3D structure modeling: Added the applications: rna_cluster, rna_minimize and rna_helix
  • RNA loop modeling with stepwise assembly: This method builds single-stranded RNA loops using a deterministic, enumerative sampling method called Stepwise Assembly.
  • Remodeling RNA crystallographic models with electron density constraint: This code is used for improving a given RNA crystallographic model and reduce the number of potential errors in the model (which can evaluated by Molprobity), under the constraint of experimental electron density map.
  • Chemically conjugated docking : These extensions of the UBQ_E2_thioester protocol allow modeling of chemically conjugated proteins (such as ubiquitin tagged to a target) via isopeptide, thioester, and disulfide linkages.
  • RosettaVIP void identification and packing application: This code is intended to take a pdb file with the coordinates for a structural model of a protein with poor hydrophobic packing, and to return a list of mutations that are predicted to fill cavities in the protein core.
  • Relax pdb with allatom constraints: hese scripts relax a pdb (minimize rosetta score) while keeping atoms as close as possible to the original positions in the crystal. It is designed to be used to prepare a structure for subsequent design in rosetta.
  • Beta strand homodimer design: This code was written for a relatively singular application: finding proteins with surface exposed beta-strands, then trying to make and design a homodimer that will form via that beta-strand.
  • DougsDockDesignMinimizeInterface: This protocol was used in the accompanying manuscript to redesign the protein/peptide interface of Calpain and a fragment of its inhibitory peptide calpastatin.
