  • scorefxn: (REQUIRED) Scorefunction to employ
  • max_samples: Maximum number of total backbone combinations to be sampled.
  • selection_type: Score criterion for selection: "high" or "low".
  • pre_scoring_mover: A mover to apply after backbone torsions are set but before final scoring and evaluation (like a min mover or something similar).
  • pre_scoring_filter: A filter to apply before scoring, which could help avoid wasteful scoring of bad conformations (like a bump check filter).
  • dump_pdbs: Dump all PDBs, if true; otherwise, there will be no PDB output at all.
  • pdb_prefix: A prefix to apply to all output PDBs.
  • nstruct_mode: If true, sample a different set of mainchain torsions for each job; if false, each job consists of the whole mainchain sampling effort.
  • nstruct_repeats: Number of repeats to perform for each nstruct.
  • residues_per_repeat: Number of residues in the minimal repeating unit of this secondary structure.
  • residue_count: Number of residues in the secondary structure exemplar to be sampled.
  • repeat_count: Number of residue-repeats in the secondary structure exemplar to be sampled.
  • residue_name: Residue type of which to create the secondary structure, indicated by three-letter code.
  • residue_name_1: Residue type of which to create the secondary structure, indicated by three-letter code.
  • residue_name_2: Residue type of which to create the secondary structure, indicated by three-letter code.
  • residue_name_3: Residue type of which to create the secondary structure, indicated by three-letter code.
  • residue_name_4: Residue type of which to create the secondary structure, indicated by three-letter code.
  • cap_ends: If true, adds acetylated and amidated N- and C- termini.

Subtag MainchainTorsion: Tags describing individual torsions in the helix

  • index: (REQUIRED) Mainchain torsion index indicated
  • res_index: Residue whose mainchain torsion is being specified (if there is more than one residue per repeat)
  • value: A single value in degrees, if this torsion ought to be fixed
  • start: Starting value of a torsion range in degrees
  • end: Ending value of a torsion range in degrees
  • samples: Number of samples to be taken of the dihedral range indicated
