Loop Modeling Options

Here is a list of loop modeling options

General Instruction

-lopps:input_pdb			Template pdb file. default='input_pdb' [File]
-loops:loop_file			Loop definition file. default='loop_file' [File]
-loops:mm_loop_file			Loop definition file. default='loop_file' [File]

-loops:fast				Reduce number of simulation cycles in loop modeling. Default='false' [Boolean]
-loops:frag_sizes			(non-kic modes only) Length of fragments to be used in loop modeling (in other words, number of amino
                          		acids/residues for each segment. For each type of fragment). defaults to 9 3 1 [IntegerVector]
-loops:frag_files			(non-kic modes only) Path/Name of fragment libraries files, defaults to frag9 frag3 frag1. [FileVector]
-loops:build_initial			Preceed loopmodelling with a initial round of just removing the missing densities and building simple loop.
					Default = 'false'. [Boolean]
-loops:extended				Force extended on loops, independent of loop input file. Default='false' [Boolean]
-loops:idealize_before_relax		Idealize the structure before going into fa relax. Default='false' [Boolean]
-loops:select_best_loop_from		Keep building loops until N and choose best (by score). Default='1' [Integer]
-loops:build_attempts			Build attempts per growth attempt. Default='3' [Integer]

Kinematic Loop Modeling

-loops:neighbor_dist          Distance in angstroms to optimize side-chains near segment moved by KIC. Default='10.0' [Real]
-loops:vicinity_sampling      Sample non-pivot torsions within a vicinity of their input values. Default='false' [Boolean]
-loops:vicinity_degree        Number of degrees to deviate from (current) non-pivot torsions. Default='1.0' [Real]
-loops:kic_max_seglen         Maximum number residues in a KIC move segment. Default='12' [Integer]
-loops:remodel_init_temp      Initial temperature for simulated annealing for perturb_kic
-loops:remodel_final_temp     Final temperature for simulated annealing for perturb_kic
-loops:refine_init_temp       Initial temperature for simulated annealing for refine_kic
-loops:refine_final_temp      Final temperature for simulated annealing for refine_kic

Options affecting growing/combining of loops

-loops:grow_attempts			Total loop growth attempts. Default='7' [Integer]
-loops:random_grow_loops_by		Randomly grow loops by up to this number of residues on either side.
					Default='0.0' [Real]
-loops:accept_aborted_loops		Accept aborted loops. Default='false' [Boolean]
-loops:strict_loops			Do not allow growing of loops. Default='false' [Boolean]

Options affection choice of loops

-loops:build_specific_loops		Numbers of the loops to be built. [IntegerVector]
-loops:random_order			Build in random order. Default='false' [Boolean]
-loops:build_all_loops			Build all loops(no skip). Default='false' [Boolean]
-loops:combine_rate			Combine successive loops at this rate. Default='0.0' [Real]

Subprotocol Components

-loops:remodel				Legal values: 'no','perturb_ccd','perturb_kic'. This option controls the centroid-stage loop remodeling (where large perturbations are attempted).
                          		Default = 'quick_ccd' [String]
-loops:intermedrelax			Currently not used; Eventually may provide for a full-pose relax between centroid and fullatom
		                        modeling. default = 'no' [String]
-loops:refine				Legal values: 'no','refine_ccd','refine_kic'.
					This option controls the fullatom refinement stage of loop. modeling. Default = 'no' [String]
-loops:relax				Legal values: 'no','fastrelax','shortrelax','fullrelax'    [String]
		                        Controls whether a full-structure relax occurs after loop modeling.  Defaults to "no".
